Product Description
Completely portable, the patented controlled negative pressure technology is used to run a complete 5-step protocol in 2-3 minutes. This is not only the fastest, but also the most accurate way to conduct a quantitative respirator fit test. The Quantifit package includes a carrying case, keyboard, onboard memory and PC connections, as well as other features that allow for easy and quick testing. Speed, accuracy, and ease of use, have made the Quantifit the gold standard in respirator fit testing.
The OHD Quantifit is a highly specialized instrument which utilizes the scientifically-proven and patented CNP (Controlled Negative Pressure) technology to directly measure respirator leakage. The OHD Quantifit is accepted by OSHA and appears in the Federal Regulations governing fit testing [29 CFR 1910.134]. The Quantifit is also included in the Canadian Standards [CSA Z94.4-02] and UK HSE Standards [EN132-149].
With the OSHA approved CNP REDON respirator fit test protocol, a fit test can be performed in as little as 2-3 minutes and there is no waiting period for smokers as required with other fit test methods. The REDON protocol uses CNP technology’s superior speed and accuracy to help achieve the best respirator fit possible. The multiple donnings required assures that the worker knows how to don the respirator correctly with each use.
Here’s how the Quantifit works:
During a fit test, the respirator inlets are capped with test adapters, and the inhalation valves are removed from the mask. With the test subject holding his or her breath for no more than ten seconds, the Quantifit then establishes and maintains a slight vacuum, or controlled negative pressure, inside the mask. Since the respirator inlets are sealed, all sources of leakage into the mask are through the face-to-facepiece seal. The volume of air drawn out of the mask by the Quantifit during this short period of time is equal to the leak rate into the mask through the face-to-facepiece seal.
