The AZ 7701 CO Meter is uniquely designed to measure Carbon Monoxide concentrations in ppm. Featuring a back-lit digital LCD screen, this pocket-sized instrument is ideal for taking the CO values in enclosed spaces such as cars, hospitals, factories and other areas where air quality is of great importance.
Users can set and adjust CO Concentration Alarm for different purposes, making this unit adaptable to your needs. The AZ 7701 CO Meter can be calibrated by the user for added convenience.
