TRUST: ** 1 year limited warranty ** Arrives factory calibrated ** 100% product test and verification in the USA * Best Japanese CO sensor ** 100% quality guaranteed ** Product Description Car, Vehicle, Aircraft Carbon Monoxide Detector Easy to Use. Small. Easy One Button. The original FORENSICS DETECTORS vehicle and aircraft CO gas detector, made with HIGH-QUALITY Japanese sensor technology for maximum protection. Low level alarming to prevent CO exposure from exhaust leaks or polluted air entering the airplane or vehicle. Have peace of mind and take preventative care to avoid headaches, nausea, and fatigue. Regular CO alarms for the home are too slow, alarming in 60 to 240 minutes over 70 ppm - allowing fatigue and drowsiness to lead to accidents. The FORENSICS CO detector has been tested and confirmed at high altitudes for aircraft reliability. USA Calibration. Max Accuracy. Have the highest confidence in your gas detection accuracy. Possible only with best calibration practices to USA NIST Traceable Sources. Calibration qualified in the Forensics Detectors laboratory, located in Los Angeles, California, USA. Low Level CO Alarm. 9ppm (LED). 25ppm (Buzzer). CO alarms are set at 9 ppm with red LED 25 ppm with audible buzzer sound (70 dB). To ensure max protection, alarm levels were chosen as recommended by the World Health Organization (WHO), Environmental Protection Agency (EPA), American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), and American Conference of Governmental Industrial Hygienists (ACGIH).
