Allegro fit test kits facilitate safe and fast qualitative respirator fit checking for reusable mist, dust and disposable respirators. The denatonium benzoate test kits give a bitter taste to indicate a breakthrough in respirator fit. These kits are equipped with a pre-drilled plastic cap and have disposable glass ampules for pouring solution easily into the nebuliser and reduce the possibility of contamination. These nebulisers are made of polycarbonate plastic to prevent breakage and can be disassembled for washing. Allegro 2050 standard smoke test kits have a glass container containing stannic chloride for pungent odour and rubbed caps for protection & storage. The brand's 0203, 2050 and 2055 Series kits are easily available on Raptor Supplies.
