Reliable Protection Without False Alarms

The Quantum Group has successfully combined biotechnology with infrared engineering to produce reliable and false alarm-free carbon monoxide sensing elements.

Only COSTAR carbon monoxide detectors offer this level of reliability. Liquid electrochemical sensors (used in most competitor's detectors) are sensitive to many common household gases, particularly from cleaning products and air fresheners. Their frequent false alarms can lead people to ignore valid alerts, with fatal results. COSTAR detectors, on the other hand, react only to CO gas, and will not react to gases found in household products.
