The QuantiCheck is the world’s first quantitative user seal check device. It was designed to allow you to go above and beyond the set subjective standards for a user seal check. Used in conjunction with an approved fit test program, the QuantiCheck indicates to the user that an adequate seal has been made or if adjustments are needed every time the mask is worn.
External carriers fit underneath or on top. Made from 3-Layer GORE-TEX laminate proven to perform under the most strenuous conditions, keeping you warm and dry.
