The UEi Personal CO Meter COA2 represents measureQuick’s first integration with a personal carbon monoxide detector, adding a critical safety layer to combustion testing workflows. With direct Bluetooth connectivity, technicians see live ambient CO readings displayed in the measureQuick app throughout furnace, boiler, and water heater diagnostics. When CO levels exceed safe thresholds, the app delivers automatic warnings – no need to check a separate device or rely on audible alarms you might miss in a noisy mechanical room.

The COA2 functions as both a standalone detector and a connected smart tool. A three-color LED provides quick visual assessment of ambient conditions, while the built-in audible alarm activates at 35 ppm. The integrated sensor self-test verifies CO sensor function before each use, eliminating uncertainty about detector reliability. For extended monitoring during system burn-in or heat exchanger testing, the auto power-off function can be disabled to capture readings over longer periods.

When paired with measureQuick, ambient CO data becomes part of your diagnostic documentation. This creates a complete safety record showing environmental conditions throughout the service call, valuable for both technician protection and liability documentation. The compact design with belt clip keeps the detector in your breathing zone while your hands stay free for diagnostics.
