Respirator fit testing made easy with the PORTACOUNT® Plus Respirator Fit Tester and N95-Companion™. The automated instrument directly measures respirator fit factors as the wearer performs dynamic moving and breathing exercises, removing guesswork and human-variable influence. Results are immediate with clear pass/fail outcomes, using FitPlus™ software to streamline the process. It supports many tight-fitting respirators and full-face masks, with OSHA recognition and quantitative N95 disposable testing via the N95-Companion accessory.

Respirator Fit Testing PORTACOUNT® Plus Respirator Fit Tester and N95-CompanionTM Fit Test the Easy Way! Fit Testing Made Easy Respirator fit testing doesn’t have to be difficult. You can make fit testing easier and increase your confidence in the test results by using the PORTACOUNT Plus Respirator Fit Tester. Anyother way is the hard way! The PORTACOUNT Plus is the easy, hassle-free way to reliably fit test a variety of respirator types. The PORTACOUNT not only eliminates the guesswork found with other testing methods, it also reduces the amount of work associated with fit testing in general. Plus, with the convenient FitPlus™ software that comes with each instrument, you can streamline the fit testing process even further by letting your computer do the work. The PORTACOUNT makes a direct measurement of respirator fit factors. There are no error-inducing assumptions made to calculate “equivalent” fit factors. The measurement is made while the person simultaneously performs dynamic moving and/or breathing exercises designed to stress the respirator seal in ways that simulate anticipated workplace motions. Eliminate the guesswork The PORTACOUNT eliminates the human variables associated with qualitative methods. Variations in sensitivity to the challenge chemical or lack of cooperation can’t influence the test results because the employee makes no decisions. And, unlike other methods, the PORTACOUNT results are immediate and unambiguous. The PORTACOUNT Plus performs the fit test and delivers a “pass” or “fail.” It’s that easy. The PORTACOUNT won’t let you measure respirator fit incorrectly because the entire process is automated. Once the fittest is started, the PORTACOUNT goes through a programmed sequence. There is no opportunity to take shortcuts or skip critical steps. Compare that to qualitative methods like saccharin, Bitrex®, banana oil, and irritant smoke that involve tedious manual procedures. These procedures are often done incorrectly, thereby invalidating the fit test. OSHA accepted The PORTACOUNT has been accepted by OSHA for compliance with all fit testing regulations since 1988. Recent standards, including the new OSHA respiratory protection standard 29CFR1910.134, specifically recognize the PORTACOUNT and provide specific protocols. Fit test any tight-fitting respirator The PORTACOUNT can be used to fit test almost any tight-fitting respirator including elastomeric half-and full-face masks, PAPRs, SCBA, and even disposable (filtering-facepiece) respirators. Positive-pressure masks must be temporarily converted to negative-pressure mode per regulatory requirements prior to fit testing. Series-95 disposable masks require use of the N95-Companion™ accessory. Fit test in the employee’s own mask You can fit test with conventional probed test masks or use a fit test adapter to test people in their own respirator. Fit test adapters allow you to eliminate hygienic concerns associated with sharing a test mask and also facilitate simultaneous integrity testing of the respirator itself. Fittest adapters are available for most popular respirators. They can be obtained through TSI or directly from your respirator manufacturer. Easy to use The PORTACOUNT Plus eliminates the awkward fit test hoods and chemical exposure concerns associated with other fit test methods. It uses the microscopic particles that exist in ambient air to measure the fit factor directly. The PORTACOUNT measures the concentration of these particles around the person’s head and then measures the concentration of those particles that leak into the respirator. The ratio of these two numbers is the fit factor. A fit factor of 100, for example, means that the air inside the respirator is 100 times cleaner than the air outside. The PORTACOUNT measures a fit factor for each of the fit test exercises and then computes an overall fit factor for the entire test, along with a pass or fail indication. Unlimited fit te

FAQs

How does the PORTACOUNT Plus measure respirator fit factors?

It directly measures fit factors by using microscopic ambient air particles and calculating the ratio of particle concentration around the head versus inside the respirator during dynamic exercises.

What kind of results does the PORTACOUNT Plus provide?

It performs the fit test and delivers an unambiguous “pass” or “fail” indication, with results available immediately.

Can the PORTACOUNT Plus be used for N95 disposable respirators?

Yes. The N95-Companion™ accessory works with the PORTACOUNT Plus to enable quantitative testing of N95 disposable respirators, forming a complete fit testing solution.
