The Model 7515 is a cost-effective meter for carbon dioxide (CO2) measurements. The Models 7525  and  7545 simultaneously measure and data log multiple parameters. The Model 7525 measures CO2, temperature, humidity and calculates the dew point, wet bulb temperature and % outside air. The Model 7545 adds carbon monoxide (CO).

Applications of IAQ-CALC Indoor Air Quality Meters:

  • Verify building HVAC system performance
  • Examine building IAQ conditions to optimize worker productivity
  • Comply with regulations and guidelines
