Completely portable, the patented controlled negative pressure technology is used to run a complete 5-step protocol in 3 minutes or less. 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. While old technologies are sometimes hard to give up because, “we’ve just always done it that way,” the OHD Quantifit offers an impressive array of advantages that can dramatically improve your respirator program. Within the first ten seconds of testing, you will know whether the respirator user has a basic fit or not. And the OSHA accepted CNP Redon protocol takes as little as two to three minutes. If other quantitative fit test instruments measured accuracies of less than 40%*, why put your employees at risk?
