Respirator Exhalation Valve Air Tightness Tester 2L/Min

Respirator Exhalation Valve Airtightness Tester

MODEL: SM 4311AB

Respirator Exhalation Valve Airtightness Tester is used to test the airtightness of the exhalation vale of the respirators.

The exhalation valve is sealed on the exhalation valve test fixture in an airtight way, and the vacuum pump is used to pump air to make the exhalation valve bear a certain pressure and detect the leakage flow of the exhalation valve.

SM4311AB tester can meet the requirement of GB 2626 and JIS T8151.
