TSI 8038 PortaCount Pro+ Respirator Fit Tester



The only commercially available instrument in the world that can quantitatively fit test all tight fitting respirator face masks, including all N95, P1, P2 and P3 filtering face piece respirators.

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 TSI 8038 PortaCount®   Pro+ Respirator Fit Tester eliminates the guesswork associated with tedious and error-prone qualitative fit test methods. If the mask requires fit testing, count on the 8038 to provide the fastest, easiest and best HSE (UK) and OSHA (US)-compliant fit test method.
