Portable CO2 Meter

The meter measures CO₂ level, air temperature, dew point, wet bulb temperature and humidity. Poor indoor air quality is considered unhealthy because it causes tiredness, loss of ability to concentrate, etc. The portable CO₂ meter uses NDIR (nondispersive infrared) technology to ensure the reliability and long term stability. It is useful in verifying air ventilation control.
