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 Differential pressure detection instrument
Fill the product with a certain pressure of gas, balance, detect (by detecting the change or drop of the gas pressure to determine whether the product is qualified or not), and exhaust.
