The air tightness test is carried out using computer control, manual operation mode and air as the medium.Air tightness testing equipmentApplying pressure to the inside of the sealing box can detect the sealing degree and determine whether there is leakage in the sealing box. The pressure parameter is -80 to 120kpa, and the pressure accuracy is 0.1Mpa.
