This document describes the features and functionalities of the CO210 Carbon Dioxide Monitor and Datalogger. The meter can measure and log CO2 levels, air temperature, humidity, date, and time, and comes with visible and audible alarms. It is an ideal instrument for indoor air quality diagnosis.
The Extech CO210 is a handheld instrument designed to measure and datalog carbon dioxide (CO2), air temperature, and relative humidity. It features visible and audible alarms to warn users when CO2 levels exceed set limits, making it suitable for indoor air quality (IAQ) diagnosis. The device includes an LCD display showing real-time readings, date, time, and air quality status (GOOD, NORMAL, POOR).

It takes 2 minutes for the CO2 sensor to respond to operating environment changes.
The default upper limit for the GOOD level is 700ppm.
Hold down the SET, ▲, and MIN/MAX ▼ buttons simultaneously for more than 1 second.
Calibrate outdoors on a sunny day with good ventilation and fresh air where the CO2 level is approximately 400 ppm.
