The new PortaCount Respirator Fit Tester is a quantitative respirator fit tester. It features intelligent touchscreen solutions that support respiratory protection programs from training through compliance. The PortaCount Fit Tester Model 8040 provides a consistent and objective testing experience across respirator types equipped with ?99% efficient filters. FitCheck Mode shows in real-time how respirator fit changes throughout donning and adjustment, helping users select the right mask and identify the best fit more quickly. Video animations guide staff through proper fit test exercise movements during a fit test, providing a consistent testing experience and freeing fit test administrators to multitask. Group fit testing allows administrators to test up to four personnel with four PortaCounts simultaneously.
