The Extech CO100 Carbon Dioxide (CO2) Monitor is designed for air quality control and health control by measuring Carbon Dioxide level in areas where CO2 could be a concern. The measured CO2 value in ppm (parts-per-million), Temperature, Humidity and Time will be displayed on the LCD along with three CO2 status indications: Good (0 to 800ppm), Normal (800 to1200ppm), Poor (>1200ppm). An acoustic alarm sounds when the CO2 level exceeds a defined level. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
