It prevents loss of money from large-scale recall of damaged products. It is also an insurance policy against a possible costly lawsuit which can affect your brand reputation adversely.

A quality assurance for both customers and retailers with guaranteed freshness along with an increase in shelf of the product. With an increase in demand for RTE(Ready To Eat) food products, there is a demand for higher safety procedures in packaging which can be fulfilled by leak detection.

In case of gas or chemical leaks, leak detection is absolutely necessary and safeguards you against possible loss of life too.

At an individual level, it can decrease your water bill resulting from leaky faucets or pool leaks. Besides, these leaks only get worse over time leading to your money, literally going down the drain.


The leak detection method depends purely upon the accuracy required and the kind of product. A mix of various leak detection methods can be used to get the best possible results.

Following are some of the leak detection methods commonly used:


Since pressure in an important element in a sealed container, application of high pressure makes the leak more noticeable (Over-pressure technique). Tins and cans are also submerged in water to make the leaks show up in the shape of bubbles and is known as underwater bubble emission.

Uses: mainly food containers


This method mainly comprises the detection of elements such as hydrogen, radioisotopes, or helium which are added to the system and detected externally. Gas sniffing is a method which uses helium detectors which senses the presence of helium on the container.

Uses: Mainly for food and other air tight containers.


In this method, acoustic vibration waves are used to propagate high pressure gases and fluid leaks. This requires the use of an ultrasonic microphone. This method is usually combined with the other methods to give the most accurate results.

Uses: High pressure gas and water leaks, refrigerants, etc.


This method is used to track surface breaking defects in metals, ceramics, or plastics. It is based on the concept of surface tension.

Uses: In plastic or metal bodied machines, ceramic tanks, pools,etc.

Apart from installing the leak detection equipment, it is imperative to keep the maintenance of theequipment up-to-date. A well-planned system and schedule must be followed for this purpose.

It is seen that the cost of setting up leak detection is a one-time cost and quite low as compared to the possible losses. However, as a business owner or even an individual who is investing in leak prevention equipment, you should research well before investing in any kind of equipment as per your own specific needs.

Top 4 Methods of Leak Detection and Advantages

Posted on Leave a commentPosted in Leak Detection

Leak detection is a method where leak detectors are used to check the existence of a leak in a given commodity. The technique involves sealing of containers to detect any form of leakage. There are several detection methods, which are classified, as internal, or external. However, the technique used depends on where the leak detection equipment is placed.

Leaks are known to be the last effects after corrosion. The deteriorated container tends to break, exposing the contents in the container. Luckily, with the help of the sophisticated technology of leak detection equipments, corrosion is discovered before it gets to a level of exposing the materials. The detection method incorporated depends on the type of element used. There are four commonly used methods of Leak detection types (LDS)

Methods of Leak Detection System

The incorporation of leak detection equipments depends on the type of materials to be tested more so on the detection method and the detection mechanism used. The methods include:

1. Pressure Method

Pressure is an important element in a sealed container. For this reason, Leak detection equipments greatly depend on the available pressure in the sealed containers. A pressure drop or an increase in a vacuum chamber indicates that there are high chances of a leakage in a given container. Application of high pressure in the containers can make the leak to be more noticeable. Additionally, coating the outside of a tin with soapy water makes the detection noticeable since bubbles will be formed on the leaked areas.

2. Chemical Detection Method

Majority of leak detection mechanism involves the detection of elements such as hydrogen, radioisotopes, or helium. The elements are added in the system and detected externally using a suitable method. In addition, gases can also be used-the method is known as gas sniffing. Gas sniffing involves the use of helium detectors whereby the equipment is capable of sensing or sniffing out the presence of helium on the containers. Helium detection is the most used method in leak detection due its effectiveness and ease of functionality. Further, Helium detectors functionality is enhanced due to the use of mass spectrometry it incorporates.

3. Acoustic Methods

This method uses acoustic vibration waves. The waves are capable of propagating high-pressure gasses and fluid leaks. However, this method requires the technicalities of an ultrasonic microphone. The highly sensitive microphone is able to pick up the loudest of the noise emanating from the acoustic vibration waves. Additionally, for efficient and more accurate result, acoustic method in conjunction with other methods offers incredible results.

4. Dry penetration method

Dry penetration is also known as penetrant testing (PT). It is a commonly used method used to locate and track surface breaking defects in metals, ceramics, or plastics. The general basis of this methodology lies in the chemistry of understanding surface tension. The penetrant is applied on ferrous and non-ferrous materials to detect forging or welding surface defects. The defects are usually as a result of leaks, hairline cracks, or surface porosity.

Advantages of Leak Detection in Food Packaging

Guarantee of food freshness to retailers and consumers is a key aspect in food packaging. For this reason, package leak detection is a competitive advantage to guarantee longer shelf life and an appealing presentation to the consumer. Below are several advantages of using leak detection equipment in packaging food products:
• Guarantees freshness to all users of the product
• Quality assurance in the documentation of food products makes it easy for consumers and retailers to purchase the products.
• Prevents needless returns, loss of prestige, and loss of consumers

Tips for Maintenance of Leak Equipment for Detecting Leaks in Food Packaging

Posted on Leave a commentPosted in Leak Detection

Food packaging helps to keep contaminants out of processed, fresh and frozen food. The packaging also protects the food from situational problems such as moisture loss, freezer burn and physical damage. In order to ensure that the leak equipment that is used for detecting leaks in food packaging is in good condition, manufacturing and packing facility managers should follow these maintenance tips.

Follow the Manufacturer’s Maintenance Schedule
Most pieces of leak equipment come with an owner’s manual. The owner’s manual should detail the manufacturer’s specifications for maintenance. The maintenance requirements and frequency of each action should be explained. If the equipment has a manufacturer’s warranty, it is important that the maintenance schedule be followed in order to maintain the terms and conditions of the warranty. Some pieces of leak detection equipment must be serviced and repaired by factory-trained technicians. Be sure to find out if this is the case for your equipment. If it is, only use a qualifying technician to do the repairs.

Regularly Test the Leak Detection Equipment
It is also important for the leak equipment to be tested on a regular basis. The frequency of equipment testing should depend on the throughput of your facility. It might also depend on the manufacturer’s specifications. Each piece of leak detection equipment will have different testing requirements. Be sure to put the machine through testing conditions that are similar to the real-world conditions, such as testing it first thing in the morning after the machine has not been in use over a weekend or holiday. It should also be tested after it has been working for many hours, such as at the end of of an 8-hour shift.

Set Up an Automated System for Maintenance and Testing Reminders
If your facility’s leak equipment is automated, consider setting up an automated system to alert you to the need for maintenance. For example, if the manufacturer specifies that maintenance of the unit is needed after the equipment checks 10,000 units, have the equipment alert you at the 9,000 units point. If you want to implement a system of randomized testing of the leak detection system, program the system to generate a random number and test the system after that many units have been processed. Be sure to keep all of the results from your testing. You may need to have the records in order to prove that your facility has been diligent with the testing and maintenance of the food packaging systems.

Handling leak Detection for food packaging

Posted on Leave a commentPosted in Leak Detection

Food manufacturers stand to incur substantial losses whenever their food products test positive for even very small leaks. In fact, if the food products have already been dispatched, fixing the leak problems can be an extremely expensive ordeal for the company. If the leaks are not detected in real-time during the packaging process, then the food company will have to do a food recall which gravely hurts the company’s reputation. In order to avoid harming the brand reputation of your food products, you should consider investing in leak equipment that will help your packaging staff handle the food leakage beforehand.

It’s also important to understand how the leakage is detected. The detection is pretty simple because it’s all about when the packaging defect meets an already determined criterion. For instance, the pressures generated with the packaging when they are being distributed and the consequent relationship between the micro-organisms and the leak size.

Canned Goods

Leak spoilage happens when micro-organisms enter the container of canned food causing contamination. Research has proved that leak spoilage is the main cause of post-process contamination resulting in loss of sterility in the product. Hence most of the food poisoning incidents that occur at the consumption stage are caused by this type of post-process contamination.

Flexible and Semi-Rigid Packaging

Although this was developed as an option for canning, it can also experience leakage. The various layers of polymers and metals used in making the packages are designed in such a way that they offer sturdy barrier features. A leak occurs in the flexible and semi-rigid packaging when food gets entrapped in the seals or when they wrinkle slightly causing holes on the seal area of the package. In other words, the seal contamination, in this case, is mechanical and is due to poor control of the sealing structures. You should ensure that high standards of the material being used have been met because if temporary holes appear in the packaging material, leaks can also occur.

The pinholes in these types of packaging can be controlled by avoiding burst and seal creep. These are simple defects that often occur during the storage and distribution of the packages. To maintain sterility of these type of package, sealability, and peelability ought to be observed.

How Leaks Are Discovered

Besides employing all your QA/QC processes such as searching for abnormalities via sight and touch, you should consider investing in a credible leak equipment for detecting the leaks. Leaks can cause big problems to the reputation of your brand and should be controlled by all possible means.

Leak Detection : Know These Leaks and Prevent Them

The states of holes (breaks, gaps, porosity, harms, and so forth … ) are altogether different, obscure and non-uniform. Along these lines it is difficult to gauge their sizes with any geometrical measurement aside from obviously on account of a perfect or fake hole as utilized for alignment. How then to characterize the release estimate? A for the most part acknowledged strategy turned into the perception of gas or liquid course through it in specific states of temperature and weight distinction.

Radioisotope strategy is valuable just to test hermetically fixed segments. They are put in a chamber which is to be cleared and loaded with radioactive tracer gas (typically krypton 85) using apt Leak Detection Equipment.

Overpressure techniques can be performed by liquid or gas with which the tried component must be filled. As a liquid normally the water from house establishment is utilized.


Halogen spill identifiers are utilized as a part of the indicator test mode (to 10-3 mbarl/s), requiring that the framework be pressurized with a gas containing a natural halide, for example, one of the Freons.

Use of Leak Detection Equipment on Manufactured Products

Posted on Leave a commentPosted in Leak Detection

Growth in technology and economy in Canada has brought an increased usage of canned and packaged products. Faulty food packaging would lead to great losses and destruction of a company’s brand. To curb this problem, the manufacturers should aim at getting reliable leak detection equipment. The leak equipment ensures that the package is super tight by locating any pin-sized holes and leaks found on any product before it gets to the consumer. There are different leak detection equipment that vary depending on the type of material being packaged.

Offline Versus Online

Leak equipment uses either offline or online detection methods. Offline detection system requires the operator to perform the leak detection process manually. The system has a sensor that reports results of a hole and its location. The package remains intact when the sensor fails to detect a leak. In the online leak detection system, the operator feeds quality requirements to the system. The products then move along a conveyor belt, and the systems alert the operator if it detects a leak from a product.

Various Leak Detection Techniques

There are different methods used in detecting leaks from products to determine the seal’s integrity. Some of the most common methods include:

• Gas Leak Detection

The manufacturers use hydrogen, helium, and carbon dioxide to trace any leak on a package. They place the product in a closed airtight chamber and flood it with the gas and a detector gives data about the leaks and its size too.

• Bubble Emission Leak Testing Method.

It is one of the simplest methods used in the detection of leaks. The manufacturers submerge all products in water and close the lid. A package with a leak releases some air bubbles and shows the location of the bubble.

• Dry Chamber Leak Testing

The method is ideal for the liquid products with a little air space in them. The manufacturers place the item on a dry chamber that has a dry absorbent paper. They then draw the vacuum to the package and a wet absorbent paper confirms the presence of a leak.

Importance of Leak Detection

All packages contain a seal that indicates the quality of the products, and a broken one is a sign of a faulty package. Other reasons why manufacturers should be keen on food packaging include:

• When a package has a leak, the expiration date does not match performance leading to negative reviews and the low popularity of the brand.

• A leak on the products exposes it to the various contaminants in the surrounding leading to poor quality or destruction of the items. Leak detection also lowers the operational costs emanating from the large-scale product recalls.

Leak Equipment Can Help You Fix Your Pool

Posted on Leave a commentPosted in Leak Detection

Having a swimming pool on your property can be a wonderful thing, at least during the warmer months. However, as you have probably noticed since having your pool, taking care of one can be a whole lot of work. For example, even if your pool is newer or if you have been serious about taking good care of it, you have to worry about things like leaks causing problems. Luckily, a company that has leak equipment and that focuses on leak detection can help you with this.

Leaks Can Appear in Your Pool Over Time

Many people never really think about their pool leaking, but no matter what type of pool you have, this is always an option. Concrete might be strong, durable and built to last, but cracking and crumbling is something that can happen over time. After all, your concrete is exposed to water constantly, which can cause it to wear out more quickly. The problem is that it can be tough to find a leak in your pool if you don’t have the right equipment. Luckily, this is where a leak detection company can help you out.

Have You Noticed Signs That Your Pool is Leaking?

If you aren’t sure of whether or not your pool is leaking, there are a few signs that you can watch out for. One of the main ones — and one of the easiest to catch — is if your pool is losing water. It’s not abnormal for a pool to lose water and to need to have water added every now and then; for example, when it’s warm outside, you have to worry about water evaporating, and there is also a chance that people who are using your pool occasionally splash water out of it, which can lead to significant water loss over time. If you feel that your pool is losing more water than it should be, however, a leak detection company can use its leak equipment to get to the bottom of the problem.

Have Your Leaks Repaired

One thing that you should know about pool leaks is that they will often get worse on their own over time. If ignored, your pool might slowly become in worse and worse shape. For example, a small crack in a concrete pool could slowly get worse. This is why it’s so important to look for leaks and have them repaired as soon as possible.

As you can see, leak equipment can be used to help you fix your pool. If you have never worked with a leak detection company, consider contacting one so that you can find out more about finding and getting rid of leaks.

What to Do If You Find or Buy Improperly Sealed Food

Posted on Leave a commentPosted in Leak Detection
When food is processed and packaged in a factory, sophisticated machines such as a leak detector are used to ensure that packages are properly sealed. This is done to keep the items inside fresh as well as to keep potentially harmful foreign objects out. However, even in a best case scenario, there may be packages that slip through quality control and make their way to grocery stores or other retailers.

Report the Problem Right Away

The best thing that you can do is to report the problem as soon as you notice it. This may mean that you go to the customer service desk at the grocer or retailer where you buy the product. You may also want to notify the produce or grocery department manager as well as that will allow him or her to stop future orders until the problem is resolved. Finally, you should write a letter to the packaging company or to the FDA to report the issue directly.

The Problem May Be at the Retail Level

In some cases, food may have been properly packaged at a plant but improperly packaged later on at the store or public market. For instance, someone may have used store bought lettuce to make a salad that was sold in individual containers that were not properly covered. In that scenario, try to find the person who sold you the food and point out the issue. Typically, the seller will take steps to rectify the problem to ensure that no one else gets sick or otherwise gets hurt from potentially contaminated food.

Keep the Packaging as Evidence

It may be in your best interest to keep the packaging that allowed your food to become contaminated. This may make it easier for the manufacturer or store where the food was sold to put out a more specific recall or otherwise rectify the specific issue that you had with the product.

What If You Have Already Consumed Improperly Packaged Food?

If you have already consumed food that was improperly packaged, you should see your doctor immediately if you become ill. Symptoms of food poisoning are generally mild and should only last a day or two at most if you get sick at all. It may also be a good idea to make an appointment with your doctor or visit an urgent care clinic if your spouse or kids get sick from consuming contaminated food.

Improperly packaged food can be a significant liability issue for the manufacturer of that product or for anyone who sells the tainted food. Therefore, it is critical that all food packages are checked and checked again before they are allowed to be sold or consumed by the public.
