Quantifit Respirator Fit Tester

QuantiFit Respirator Fit Tester Overview

Not all respirator fit testers are the same. Not all testing methods produce the same results. Using state-of-the-art technology, the OHD Quantifit Respirator Fit Tester takes accuracy, speed and reliability in respirator fit testing to a whole new level with the whole process taking only 3 minutes.

The OHD Quantifit is a highly specialised instrument which utilises the scientifically proven and patented CNP (Controlled Negative Pressure) technology to directly measure respirator leakage. The OHD Quantifit is accepted by OSHA and is included in the Canadian Standards [CSA Z94.4-2011] and UK HSE Standards [EN132-149], as well as ANSI Z88.10-2010.

With no consumables required for operation, the Quantifit directly measures facepiece leakage. The unit precisely measures leak rate (in cc/min) by determining the amount of air that leaks into the respirator during the fit test. Other test methods infer leak, while the Quantifit is the only system that directly measures the leak.

Easy to use, the Quantifit takes the user through the test protocol step-by-step so that there is no guess-work, and very little time is needed to instruct the employee being tested. There is no instrument warm-up period to worry about, and the one-minute daily calibration ensures that the Quantifit is working within a strict tolerance.

Features

OHD Quantifit Respirator Fit Tester Features & Benefits

Proven Technology

Utilises scientifically proven and patented CNP (Controlled Negative Pressure) Technology to directly measure respirator leakage
Accepted by OSHA - Included in the Canadian Standards [CSA Z94.4-2011] and UK HSE Standards [EN132-149], as well as ANSI Z88.10-2010.

Fastest Fit Testing Available

With the OSHA approved CNP REDON respirator fit test protocol, a fit test can be performed in as little as 2-3 minutes

Multiple Donnings

Only system in the world that uses multiple donnings to ensure that the worker knows how to don the respirator correctly with each use

Easy To Use

Step by step instructions to take the user through the test protocol
No instrument warm up period
One-minute daily calibration to ensure that the Quantifit Respirator Fit Tester is working within a strict tolerance

Most Rigorous Test

Using a challenge pressure of 53.8 – 93.1 L/min, the OHD Quantifit Respirator Fit Tester stresses the mask as an employee would while breathing heavily under extreme physical conditions.
The use of air as a standard (non-varying) gaseous challenge agent provides a more rigorous test of mask fit than an aerosol agent. If air leaks into a respirator, there is a chance that the particles, vapours, or gas contaminants also may leak in. While aerosol-based systems can only see particles that may enter the respirator, CNP detects potential health hazards from contaminates smaller than particles.

On-board Data Storage

The Quantifit can store 500 tests enabling the typical user to store more than a year's worth of tests and is downloadable via the FitTrack Gold software

NIST Calibration

Ability to calibrate the Quantifit with generally available primary calibration systems assures a higher standard of test results (NIST traceable standard).

Test in any Environment

Respirator fit testing can be performed in any environment if air is present
