Hey there! As a supplier of sealing testers, I've seen firsthand how temperature can have a big impact on the performance of these nifty machines. In this blog, I'm gonna break down exactly how temperature affects a sealing tester and why it's super important to keep an eye on it.
Let's start with the basics. A sealing tester, like our Package Seal Integrity Tester, is used to check the integrity of seals on packages. It helps ensure that products are properly sealed, which is crucial for maintaining product quality and safety. But here's the thing: temperature can mess with the accuracy of these tests.
One of the main ways temperature affects a sealing tester is through its impact on the materials being tested. Most packages are made of materials like plastics, metals, and paper. These materials expand and contract with changes in temperature. For example, when it's hot, plastics tend to expand. This expansion can cause the seals on packages to loosen or even break. On the other hand, when it's cold, materials contract, which can put extra stress on the seals and potentially lead to leaks.
Let's say you're using our SN - MF2E Leak Tester to test a plastic package. If the temperature in the testing environment is too high, the plastic might expand, and the tester might give a false - positive result, indicating a leak when there really isn't one. Conversely, in a cold environment, the contraction of the plastic could create micro - leaks that the tester might detect, even if the seal was originally intact under normal conditions.
Another aspect to consider is the effect of temperature on the air inside the package. When the temperature rises, the air inside the package expands. This increase in pressure can make it seem like there's a problem with the seal, even if the seal is actually fine. Our sealing testers work by measuring pressure changes to detect leaks. So, if the temperature - induced pressure change isn't accounted for, it can lead to inaccurate test results.
For instance, if you're using our SN - MF1E Leak Tester and the package has been sitting in a hot warehouse before testing, the expanded air inside the package can cause the pressure readings on the tester to be off. This might make you think there's a leak when it's just the result of the temperature - related pressure change.
Now, you might be wondering how to deal with these temperature - related issues. Well, one of the best ways is to control the testing environment. Try to keep the temperature in the testing area as stable as possible. Most sealing testers work best within a specific temperature range. For our products, we usually recommend a temperature range of around 20 - 25 degrees Celsius (68 - 77 degrees Fahrenheit).
If you can't control the temperature of the testing environment completely, you can also take steps to account for temperature changes in your testing process. For example, you can let the packages acclimate to the testing environment for a certain period of time before testing. This allows the materials and the air inside the packages to reach a stable state, reducing the impact of temperature on the test results.
It's also important to calibrate your sealing tester regularly, especially if the temperature in your testing area fluctuates. Calibration ensures that the tester is accurate and can account for any temperature - related variations. Our technical support team can help you with the calibration process and provide you with guidelines on how often it should be done based on your specific testing conditions.
In addition to the accuracy of the test results, temperature can also affect the performance and lifespan of the sealing tester itself. High temperatures can cause the electronic components in the tester to overheat, which can lead to malfunctions and a shorter lifespan. On the other hand, extremely cold temperatures can make the moving parts in the tester more rigid, affecting its mechanical performance.


So, as a supplier, we always emphasize the importance of proper temperature management when using our sealing testers. We want you to get the most accurate results possible and ensure that your investment in our products lasts for a long time.
