Introduction 

Congratulations on your purchase of this Model CO200 Carbon Dioxide Meter. This 
meter measures CO

 level, air temp., humidity, date and time. With visible and audible 

alarms, this is an ideal instrument for indoor air quality (IAQ) diagnosis. This meter is 
shipped fully tested and calibrated and, with proper use, will provide years of reliable 
service.
