The Allegro RK-2041 Bitter Fit Test Kit provides everything required to perform OSHA-compliant qualitative fit testing using denatonium benzoate as the test agent. Designed for ease of use in the field or in controlled environments, the kit includes a lightweight, clear fit test hood, two nebulizers (one for sensitivity testing and one for the fit-test challenge), pre-measured solution ampules, and essential cleaning tools. The bitter taste generated by the solution offers a clear and immediate indicator for determining whether a respirator achieves a proper seal. Ideal for safety teams and industrial hygiene programs, this portable kit supports fast, repeatable fit testing across multiple workers and respirator models.
