Q-Trak Indoor Air Quality Monitor

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.

  • Simultaneously displays CO2, CO, temperature and humidity measurements
  • Calculates dew point, wet bulb and percent outside air
  • Large graphic display
  • Displays up to 5 measurements
  • On-screen messages and instructions
  • One instrument with multiple plug-in probe options including VOC’s and air velocity
  • Store up to 39 days of data collected at one-minute log intervals
  • TRAKPRO™ data analysis software provided for data logging, analysis and documenting results
