Product Details

Only PortaCount Fit Testers provide one consistent and objective testing experience across all respirator types, including all N95 filtering facepieces. FitCheck Mode™ and animated fit test instructions help users achieve a better fit for respirator wearers more quickly. 

FitCheck Mode shows in real time how respirator fit changes throughout donning and adjustment, helping users select the right mask and identify the right fit more quickly.

Video animations guide staff through the proper movements for each test exercise, providing a consistent testing experience and freeing administrators to multitask.
