The Extech CO210 Desktop Indoor Air Quality CO2 Monitor/Data Logger checks for Carbon Dioxide (CO2) concentrations using a maintenance free NDIR (non-dispersive infrared) CO2 sensor. Indoor Air Quality is displayed in ppm with clear Good (0 to 800ppm), Normal (800 to 1200ppm), and Poor (>1200ppm) level indication. The CO210 features a visible and audible CO2 warning alarm for out-of-range levels.
