Respirator Fit Testers

Quantitative Respirator Fit Testing. The Highest Level of Protection.

Respirator Fit Test

In many of today’s workplace environments, a respirator and a proper respirator fit test are critical components of employee respiratory protection.

Healthcare professionals, fire service and law enforcement employees, to industrial company workers have come to depend on properly fitting respirators for protection from respiratory hazards, such as chemical and environmental hazards, as well as airborne biohazards.

When implemented correctly, a respirator fit test program can help ensure that the highest respiratory protection levels are achieved through a properly sized and donned respirator.

Easy, Accurate, and Repeatable

PortaCount® Respirator Fit Testing equipment measures the fit of the respirator while the user simultaneously performs a series of moving, breathing and talking exercises designed to simulate the same movements made in the field. With step-by-step guidance, the instrument walks you through the fit test.

Once the fit test is complete, it is easy to generate reports. The test results load into a database for retrieval and regulatory compliance.
