Pressure tester: In the production process of air conditioning units and fin heat exchangers, it is necessary to inspect the product's tightness and pressure resistance. Generally, manually read the readings of the precision pressure gauge, record the pressure at the beginning of the holding pressure and the pressure after the holding time, and compare and calculate the pressure difference to determine whether the pressure resistance of the product meets the process requirements.
The pressure tester is used for pressure test, pressure holding test, and vacuum holding test using helium and nitrogen as the test medium. It is also used for refrigeration, air conditioning and other applications that require inflation pressure test and vacuum leak test. Production workshop.
