Volumetric air tightness testing instrument

Volumetric air tightness testing instrument

Air tightness tester is also called air leak tester, waterproof tester, seal tester, etc. It is called differently according to the use, but its main use is the same - to judge the amount of leakage by the pressure rise and fall method, so as to judge The air tightness of the product or component is excellent.


The working principle of the Volumetric air tightness testing instrument

There are two types of volume detection methods: direct pressure volume type and differential pressure volume type.

Ordinary direct pressure type and differential pressure type just fill the gas pressure is fixed, and the volume is not fixed, the product is large, the product is filled with more gas to reach the test pressure, and the product is small, the gas is less filled to the test pressure. These classes are mainly used to detect open products.

The direct pressure volumetric type and the differential pressure volumetric type are filled with a fixed gas pressure and a fixed volume. It is mainly used to detect fully sealed products, such as electric toothbrushes, beauty instruments, car cameras, motors, car tire pressure gauges, gastroscope capsules and other products.
