The world’s first quantitative user seal check device

Be better than compliant. The QuantiCheck® was designed to allow you to go above and beyond the set subjective standards for a user seal check.


The OHD QuantiCheck

The QuantiCheck can increase health protection and limit liability.

During gear prep, before a mission or when entering a hazardous area utilize the OHD QuantiCheck to test your mask’s seal.

Be better than compliant.

A Revolutionary Way to Enhance Your Respiratory Protection Program.

The QuantiCheck is the first quantitative user seal check device. The user engages the QuantiCheck, takes a comfortable breath and holds. At the lowest point of the negative pull, the system starts a calculation which is a proprietary algorithm that measures pressure loss from the respirator. The system simply indicates that the weakest point will be the required air entry point into the mask. The system is a static user seal check indicating the fit of the mask at the point in time the system is used.

The OHD QuantiCheck

Clean air is vital and fundamental no matter the working environment.

The OHD QuantiCheck allows the user to check the seal of a respirator with every donning.

Check with confidence.

Engineered for Fit

Performance is at the heart of what we do. Used in conjunction with an approved Fit Test program the QuantiCheck is designed to indicate to the user that an adequate seal has been made, or if adjustments are needed every time the mask is worn. The system checks not only the face seal but the whole mask system for breaches or integrity issues that could cause leaks during use.
