Portacount Respirator Fit Tester 8038

Respirator Fit Testing You Can Trust.


No other respirator fit tester can quantitatively fit test all types of respirators-gas masks, SCBAs, respirators, even N95, P1 and P2 disposable (filtering-facepiece) respirators. The PortaCount® Pro+ Respirator Fit Tester 8038 eliminates the guesswork associated with tedious and error-prone qualitative fit test methods. If the mask requires fit testing, count on the PortaCount Pro+ Fit Tester to provide the fastest, easiest and best HSE (UK) and OSHA (US)-compliant fit test method.
