3M Respirator Fit Test Solution - Bitter 55ml

3M FT-10 uses a test solution of sodium saccharin that produces a sweettasting aerosol and FT-30 uses denatonium benzoate to produce a very bitter taste. The choice between the bitter and sweet test kit is a personal one, however a small percentage of the population are unable to detect saccharinin which case the bitter test must be used. For use with the E0263 Fit Test Kit.
