Quantifit | The Gold Standard in Respirator Fit Testing
When lives depend on your equipment, there is no substitute for safety. Quantifit provides the most accurate, most verifiable fit test for respirators on the market. To ensure that your masks fit properly. To ensure the safety of your employees. We designed Quantifit for durability and portability. It’s more streamlined and lighter than previous models and includes a carrying case, keyboard, onboard memory and PC connections.
"The Chicago Fire Deparment implemented the OHD Quantifit for NFPA compliant SCBA fit testing. The Quantifit has increased our speed, accuracy and ability to manage reports using OHD's FitTrack Gold software."
"The best technology that I have found is the OHD Fit Tester. This method uses controlled negative pressure to actually quantify the size of the leak (if any) in the mask. Using air pressure as the challenge agent in fit testing gives the most accurate results and there are published scientific studies to prove it. Other quantitative methods may provide the user with a false positive or a PASS on the fit test. There is minimal chance for a false PASS result on the OHD fit tester because the air pressure inside the mask is what is being quantified. If there is a leak, it will be detected. Leaks matter even the small ones! The OHD Fit tester does not lie! Many Fire Departments have been using this technology for years."
“We are extremely impressed with the machines. They have cut our fit test time considerably! Very pleased!”

“All, I wanted to say how impressed I am with your Quantifit. I have used your competitor’s product before and in comparison your system is so simple. I also was impressed that I could not get it to pass a fit test with my beard on, whereas I could do that with other quantitative fit testers. Excellent job.”
Quantifit Features and Benefits
Complete the OSHA-approved Controlled Negative Pressure (CNP) Redon protocol in as little as three minutes. You’ll know if a user has a basic fit in as little as 10 seconds. It’s that easy. Quantifit uses no consumables, is not environmentally dependent. In fact, it uses the air in the room as the challenge agent. Read on for a full list of Quantifit’s features and benefits.
How it Works
One tube pulls a negative pressure, and to keep the pressure constant, it has to pull out any additional air that leaks into the mask. This measurement directly tells us how much air has leaked into the mask, and that leak amount is converted to a fit factor.
