  • 4 in 1 Measures: CO, CO2, Temperature & %RH
  • In-Field Calibration with fresh air
  • Programmable CO Alarm
  • USB-out for data logging


The Indoor Air Quality Meter measures CO2 levels, CO levels, air temperature, dew point, wet bulb temperature, and humidity. It is an ideal instrument for indoor air quality (IAQ) diagnosis.

This hand-held meter uses NDIR (non-dispersive infrared) technology for CO2 measurement to ensure reliability and long-term stability. It is useful in verifying HVAC systems performance and air ventilation control.
