Fit Test anywhere
in under 2 minutes with the QuantiFit2.
The QuantiFit2 performs the fastest, easiest, and most precise respirator fit test on the market, ensuring protection for you and your team.
QuantiFit2 Utilizes Patented Controlled Negative Pressure (CNP)
Perform OSHA & ISO
Approved Fit Tests
OSHA Compliance
Controlled Negative Pressure (CNP), OHD's patented technology that powers the QuantiFit2, is accepted by OHSA and appears in the Federal Regulations governing fit testing [29 CFR 1910.134].
ISO Compliance
Controlled Negative Pressure (CNP), OHD's patented technology that powers the QuantiFit2, is accepted by ISO and appears in the International Regulations governing fit testing [16975-3].
Unlimited Portability
The QuantiFit2 can perform OSHA and ISO approved fit testing in any environment: outside, inside, dirty environments, or clean. No consumables required.
As long as air is present, the QuantiFit2 can perform fit testing. Tests can be performed with no waiting period for smokers or after eating.
Proven Accuracy with CNP Technology
OHD's patented Controlled Negative Pressure (CNP) Technology directly measures respirator leakage, using air as the only challenge agent. No consumables required.
The unit measures the leak rate (in cc/min) by determining the exact amount of air that leaks into the respirator during the fit test.
Lifetime Powertrain Warranty
Our exclusive, industry-first, lifetime powertrain warranty protects the inner workings of the QuantiFit2.
Rechargeable Battery Packs
Optional rechargeable battery packs are available with more than four hours of active run time.
Interactive Troubleshooting
Each test exercise graph is captured for review, which allows users to compare results to example support graphs.

Frequently Asked Questions
Yes, the QuantiFit2 may be used outdoors and in any environment as long as air is present. The QuantiFit2 and its patented Controlled Negative Pressure technology does not require specific particle / aerosol environments like other technologies. The system is not designed to be used in inclement weather such as rain, sleet or snow. The QuantiFit2 is designed for use at temperature ranges of 5°C to 45°C (41°F – 113°F).
The HP 200 and HP 250 mobile printers work with our QuantiFit2. You can click the link here to see a full list of printers.
The amount of records the QuantiFit2 can hold is virtually unlimited from a practical standpoint. The internal storage should allow hundreds of thousands to millions of test records to be stored.

QuantiFit2 eliminates the need to delay testing on mask users that have just eaten or smoked. You can test immediately with QuantiFit2. The QuantiFit2 CNP technology enhances logistics by simplifying employee requirements prior to testing.
The Controlled Negative Pressure technology of the OHD QuantiFit2 allows the mask to be challenged in ways that are impossible, or at least impractical, for other systems. Because we use negative pressure to replicate the negative force of inhalation, the OHD QuantiFit2 can be set to increase the negative force in the mask to replicate breathing rates of over 100 liters of air exchanged per minute and measure the leak effect in only 8 seconds. Other systems might only be able to test at this level if you get the wearer to actually breathe at this high rate continuously for several minutes. Doing so with other systems would create great stress on the mask wearer!
