The QC-50 provides a quick and easy method of checking the performance of gas detection systems. The QC-50 utilizes revolutionary technology allowing a functional check (or «Bump Test») as needed or required by law. The unique QuickCheck Vials (QCV) utilizes a stable, safe and reliable delivery method allowing ease of shipment, storage and use. The QC-50 is currently available for ammonia and hydrogen chloride.The QCV used in the QC-50 are small, disposable vials with a small amount of the gas to be tested in liquid form in a sealed inner ampoule. Breaking the inner ampoule allows the liquid to absorb into a filter which then diffuses out the gas. Simply squeezing the hand aspirated bulb will allow a test concentration of gas to flow by the gas detector, verifying its operation
