Wireless Carbon Monoxide Detector

The UEI COA2 Wireless Carbon Monoxide Detector gives technicians a practical wireless solution for portable ambient carbon monoxide detection during HVAC, gas, combustion and service work. Designed for on-site testing, it helps monitor CO levels around boilers, furnaces, heaters, plant rooms, mechanical rooms and other areas where carbon monoxide may be present.

With a detection range of 1 to 999 ppm, the COA2 provides clear CO measurement for identifying potential hazards during maintenance, diagnostics and safety checks. Its wireless app connectivity and live data functions allow technicians to view readings in real time, helping support faster, more informed decisions while working on site.

Compact and portable, the COA2 is ideal for technicians who need flexible ambient CO monitoring without being restricted by fixed-position equipment or cables. It is especially useful when checking work areas, testing around fuel-burning appliances, or monitoring CO levels while carrying out service and fault-finding tasks.
