Respirator Valve Air-Tightness Tester SC-RT-N1704

The SC–RT–N1704 measures the leakage air-flow of respirator exhalation valves to verify airtightness against the latest GB 2626–2019 そして NIOSH 42 CFR 84 要件. An integrated oil-free vacuum pump automatically establishes a stable negative pressure; the test sequence is fully software-controlled, with results shown on a touch screen and printed instantly. Ideal for valve makers, mask factories and third-party labs handling incoming, in-process or finished-goods QC.
