Respirator Fit Testers

Respirator Fit Testing for the Highest Level of Protection

In many of today’s workplace environments, a respirator and a proper respirator fit test are critical components of employee respiratory protection. Fire service and law enforcement employees, as well as industrial companies and healthcare professionals 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 testing 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 real-time fit while the user simultaneously performs a series of moving, breathing and talking exercises designed to simulate the same movements made in the field. The step-by-step process is guided via the FitPro+™ Fit Test Software. The data loads into a database for easy report generation, retrieval and regulatory compliance. Stored data is easily exportable to a flash drive. 

Total MASK TestING Solutions

From quantitative fit testing equipment to mask integrity testing equipment, TSI helps you comply with regulated standards and ensure your workers' respiratory safety.

  • Passing a real-time quantitative respirator fit test proves that the face piece is sized and donned correctly, as well as provides for valuable opportunity for training. The PortaCount Respirator Fit Tester tests all types of respirators, including N95 filtering face piece respirators.
  • Testing mask integrity helps identify leaks and ensure the proper functioning of a face piece. The Mask Integrity Test Accessory (MITA), in tandem with the PortaCount Respirator Fit Tester, tests full-face respirators and CBRN (chemical, biological, radiological and nuclear defense) gas masks.
