The mask airtightness tester is an instrument used to test the airtightness of masks for self-absorbing filtered anti-particulate respirators.
Wear the mask on the test head mold matched with the mask airtightness tester, seal the inhalation valve and moisten the exhalation valve. Pneumatic vacuum pump, so that the pressure inside the mask to reach a certain negative pressure value, stop pumping, start timing, observe and record the mask pressure change value in 60s.
RF4311C tester, built-in precision pumping, high-precision vacuum pressure gauge, timer, precise control of pressure and test time.
