User Manual
This document introduces the Extech Meter Desktop Indoor Air Quality Monitor Model CO100, which is designed to measure the Carbon Dioxide (CO2) level and display it on the LCD screen. It also measures temperature, humidity, and time. The monitor provides three CO2 status indications: Good (0 to 800ppm), Normal (800 to 1200ppm), Poor (>1200ppm). An acoustic alarm sounds when the CO2 level exceeds a defined level. The meter is fully tested and calibrated and is expected to provide reliable service.
