Q-Trak Indoor Air Quality Meter

Q-Trak Indoor Air Quality Meter



Providing a comfortable, safe and healthy indoor environment is an increasingly important concern. Good air quality increases concentration and productivity. It can also reduce lost days due to absence. TSI’s Q-TRAK™ IAQ Monitor provides quick, accurate information to assess key IAQ parameters.

The Q-TRAK monitor’s state-of-the-art sensors and large, easyto-read graphics allow real-time, simultaneous display of temperature, relative humidity, CO2 and CO. The user can even review previously stored data without interrupting a test in progress.
