Quantitative Fit Testing (QNFT) Quantitative respiratory fit testing uses an instrument, the TSI PortaCount®, to measure the actual amount of leakage that makes its way into your respirator and can be used for any sort of tight fitting respirator. This method does not rely on your sense of taste, smell, or irritation in order to detect the leakage. Instead, the 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.
Our respiratory fit test technicians will also address the proper donning and doffing of the respirator, how to perform seal checks, the care, use and maintenance of the respirator, the defining differences between N, R, and P-Series respirators, as well as half and full facepiece respirators.
