AZ Instrument 7701 Digital Carbon Monoxide (CO) Detector

The AZ Instrument 7701 is a high-precision digital handheld Carbon Monoxide (CO) detector, specifically designed to monitor hazardous gas concentrations in environments such as factories, hospitals, enclosed parking lots, and vehicles. Featuring a long-life electrochemical sensor, the 7701 provides rapid and reliable diagnostics by displaying both the current CO reading and the maximum (MAX) value on its dual LCD. This device is an essential safety tool for HVAC professionals, industrial inspectors, and safety officers.

Designed for operational efficiency, the AZ 7701 comes pre-set with an audible alarm that triggers above 25 ppm, though users can customize this threshold to meet specific safety regulations. The device excels in low-light conditions thanks to its bright backlight function and offers a robust battery life of up to 300 hours. With 2-point calibration (0/500 ppm) capability and a rugged pocket-sized frame, the AZ Instrument 7701 stands as the definitive professional standard for air quality monitoring and gas leak detection.
