About This Product
The UEi COA2 is a wireless portable carbon monoxide detector designed for ambient CO safety monitoring during HVAC service calls. Its 3-color LED provides instant visual assessment of CO concentration levels, with an audible alarm triggering at 35 ppm. The CO sensor features a 5-year expected lifespan with 1 ppm accuracy and built-in self-test capability. Compact and belt-clip ready, it is designed for ambient air testing around heating equipment, not for flue gas analysis.
