Extech CO100 - Desktop Indoor Air Quality / CO2 Monitor

The CO100 Carbon Dioxide (CO2) Monitor is designed for air quality 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.

Applications include:

• Schools
• Office buildings
• Greenhouses
• Factories
• and more

ABC (Automatic Baseline Calibration)

ABC (Automatic Baseline Calibration) establishes a baseline calibration to eliminate the zero drift of the infrared sensor. The ABC function is always “ON” when the meter is turned on. ABC is designed to calibrate the meter at the minimum CO2 reading detected during 7 days of continuous monitoring (power on). It assumes that the area being tested receives fresh air with a CO2 level of approximately 400ppm at some period of time during the seven days. It is not suitable to use a desktop CO2 meter in closed areas with consistently high CO2 levels, 24 hours a day.
