Extech CO100 Air Quality Meter

The CO100 allows for the monitoring of air quality in spaces where CO2 levels can become problematic. Elevated levels can negatively impact health, concentration, and overall well-being. The CO2 level should be monitored in all areas where many people gather for extended periods. The display shows the measurements of CO2, air temperature, and humidity, along with the time and date simultaneously. For easy assessment of the CO2 level, an index symbol is also displayed: good (0 - 800 ppm), normal (800 - 1200 ppm), poor (>1200 ppm). An alarm signal will sound if the adjustable alarm threshold is exceeded.
