Respirator fit testing doesn't have to be difficult. The PortaCount Plus is the easy, hassle-free way to reliably fit test a variety of respirator types. It not only eliminates the guesswork found in other testing methods, it reduces the amount of work associated with fit testing in general. Plus, the FitPlus™ for Windows software streamlines the process even further by letting your computer do the work.

The PORTACOUNT makes a direct measurement of respirator fit factors. There are no error-inducing assumptions made to calculate "equivalent" fit factors. The measurement is made while the person simultaneously performs dynamic moving and/or breathing exercises designed to stress the respirator seal in ways that simulate anticipated work place motions.
