Extech CO220 Desktop Indoor Air Quality CO2 Monitor measures CO2 concentration, air temperature, and relative humidity. The CO200 includes a 99 Memory Datalogger for storing and retrieving readings with date and time stamping.
The audible alarms make this is an ideal instrument for indoor air quality (IAQ) diagnostics. Carbon dioxide (CO2) is a gaseous component of the earth’s atmosphere. The concentration of CO2 in natural ambient air is approximately 0.04% or 400ppm.
The Extech CO220 Desktop Indoor Air Quality CO2 Monitor calculates statistical weighted averages of TWA (8 hour Time Weighted Average) and STEL (15 minute Short Term Exposure Limit).
The CO220 has a maintenance free NDIR (non-dispersive infrared) CO2 sensor and can manually store/recall 99 readings. Supplied with Australian AC power adaptor.
