The FT11 Sweet Fit Test Solution assesses the respirator-face seal on all types of particulate or gas/ vapour respirators, thus conforming to the OSHA fit testing requirements for respirators. If the protection provided by the mask is no longer satisfactory, the user will notice a sweet taste when the test is performed. The 55ml bottle is sufficient to perform 30-40 tests.
