Imagine if the battery of a new energy vehicle leaks because of poor sealing, or a high-end cell phone enters water because of airtightness problems, not only will users go crazy, but also companies may lose a lot of money.

In this article, we'll take you on a journey into the wonderful world of hermetic testing, talk about how it works, and take a look at the top 10 brands for 2025. Whether you're a veteran engineer or a newcomer to the industry, this guide will help you find the most reliable hermeticity testing solution.

I. Air Tightness Instruments: Small Size, Big Power

The task of an airtight meter is simple yet critical:It is responsible for checking the product for any air or water leaks, thus ensuring that the product is stable, reliable and foolproof in all usage scenarios.

principleIt's not really that complicated.By applying positive or negative pressure, or by using a "detective gas" such as nitrogen or helium, and observing the flow of the gas or the change in pressure, we are able to quantify the sealing status of the product and even identify leakage points.

Take a look at a few mainstream methods:

• Positive/negative pressure method: Mimic real use environment, support IP65~IP69 waterproof test, consumer electronics regulars.
• differential pressure: Compare the pressure difference between the product under test and the standard part, and accurately capture tiny leaks, perfectly suited for high-precision scenarios such as die castings and water-cooled plates.
• flow rate method: Real-time monitoring of gas flow changes, suitable for leakage rate testing, such as capillary tube, waterproof breathable membrane, easy to operate and save money.
• helium detection: Helium is used as a "probe" with detection accuracy up to 10^-6 mbar-L/s, a favorite of the aerospace and semiconductor industries.

These technologies have made hermetic gauges the 'quality stewards' of the manufacturing industry. For example.In the production of new energy batteries, the hermetic tester can reduce the scrap rate 20%~40%Save money and stay safe.The2025.Helium detection method is expected to account for more than 30% of the market share due to its ultra-high accuracyThe
