TSI 8048 PortaCount 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.

The new TSI 8048 PortaCount Respirator Fit Tester is a quantitative respirator fit tester. It features intelligent touchscreen solutions* that support respiratory protection programs from training through compliance.

Only the 8048 provides one consistent and objective testing experience across all respirator types, including all N95 filtering face pieces using N95-Companion™ technology. New features like FitCheck™ Mode and animated fit test steps now help users achieve a better fit for respirator wearers more quickly. Video animations guide staff through the proper movements for each test exercise, providing a consistent testing experience and freeing administrators to multitask.
