- 1-3 minute respirator fit testing
- With the OSHA-approved 5-step Redon Protocol, which can only be used with Controlled Negative Pressure technology (The FitTester 3000 and the Quantifit), a typical fit test can be completed in less than three minutes. And with the improved automation of the Quantifit, it's actually quicker and easier than ever!
- On-board data storage (more than 500 tests)
- The Quantifit can store more than 500 tests so that the typical user can store a year's worth of tests or more. The data can be downloaded to FitTrack software or backed up to a memory stick as a text file for safe keeping.
- USB keyboard and printer connection
- The Quantifit comes with a USB keyboard for data entry (employee ID and name, and all mask information). Add the optional printer, and the Quantifit system is all you need -- no personal computer necessary.
- So easy to use that the subject can test himself
- The Quantifit is more automated, requiring less interaction with the user. And with clearer instructions and simpler operation, many users will be able to do a self-test with speed and ease.
- USB thumb-drive storage and data transfer
- With the ability to connect a thumb drive or memory stick, data can be backed up or transferred to a computer with ease.
- Increased automation during testing
- The Quantifit automatically saves the test step when the minimum criteria is met. Better instructional screens also make the Quantifit easier to use and faster than ever.
- USB Computer interface
- Gone are the days of serial interface, now with USB connections, this connects the Quantifit through the included FitTrack software, or it can be used for data transfer into FitTrack.
- Firmware upgrades and improvements may be downloaded from the internet
- Whenever changes and improvements are made to the Quantifit, no need to send it in for an upgrade. The upgrades are easily downloaded and upgraded with a few simple mouse clicks.
- Updated easy-to-read display
- With a backlit display set at an optimum angle, the display is easy to read in any lighting condition. Glare from above lighting is no longer a problem.
- Smaller and lighter instrument
- Not only is the Quantifit a more modern-looking instrument, but it is also smaller and lighter. And with the build-in handle, it's easy to move in a jiffy.
- Quieter operation
- Because of technological advances in microprocessing, you won't even know the Quantifit is running because it is so quiet.
- Optical knob for easier menu navigation
- The optical knob allows the user to run through the menus with ease. For long lists to wade through, the faster the knob is turned, it incrementally moves forward faster. The knob also acts as an "enter" key, so all you need is two fingers to operate the Quantifit!
- World-wide universal power connection
- The power cord has its own transformer. To work with different voltages, the user only needs to change the portion that connects to an electrical outlet.
- More audio feedback during testing
- More feedback aids in determining if a particular test has failed, or if the user is performing an incorrect action.

Advantages of Controlled Negative Pressure Method
On September 4, 2004, the REDON Protocol was written into the Federal Register, 1910.134, Appendix A. This ruling may be found on OSHA's website, www.osha.gov. Search for "1910.134 Appendix A."
With the OHD Quantifit Controlled Negative Pressure (CNP) technology, you've always been able to check for mask leakage in as little as 8 seconds. Now, with the REDON protocol, you can perform an entire respirator fit test in as little as two to three minutes.
While the protocol has been shortened to meet the strengths of CNP, studies show that the REDON protocol actually yields a more conservative result compared to that of the previous OSHA protocol. The test protocol requires three separate donnings, which is one of the most critical steps in wearing a respirator. The multiple donnings can be very educational in implementing proper use and fit of a respirator.
With proven scientific accuracy and a short test time, there are no down sides to the OHD FitTester 3000 Controlled Negative Pressure technology. This win/win situation allows workers to be more safely tested in a shorter amount of time.
The Quantifit can be used with optional respirator fit test adapters from the following manufacturers 3M Company, AO Safety, Bullard, Bacou/Dalloz, Cairns, Draeger, Glendale, International Safety Instruments, Interspiro, Kemira, Lab Safety, Mine Safety Appliances, Moldex, North Safety, Protech, Racal, Respiratory Systems, Inc. Scott, Survivair, and Wilson.
Ordering Information
While you may use the Quantifit with a personal computer for more advanced record keeping, the unit can do everything needed for a quantitative fit test without a PC.
Each Quantifit Respirator FitTester includes a triple-tube cable, hand-held start switch, USB keyboard, FitTrack software, universal power cord and hard case with fitted slots, roller wheels and handle. Optional Accessories include USB HP Printer (fits in the Quantifit case) and Fit Test Adapters.

5 Step CNP REDON Respirator Fit Test Protocol
Step 1 - Facing Forward - Stand and breathe normally. Hold breath for duration of the measurement.
Step 2 - Bending Over - Bend at the waist, as if touching toes. Hold breath for duration of the measurement
Step 3 - Head Shaking - For about three seconds, shake head back and forth vigorously several times while shouting. Hold breath for duration of the measurement.
Step 4 - REDON 1 - Remove the respirator mask, loosen all facepiece straps and then redon the respirator mask. Hold breath for duration of the measurement.
Step 5 - REDON 2 - Remove the respirator mask, loosen all facepiece straps and then redon the respirator mask. Hold breath for duration of the measurement.
