NEW AQM4 Air Quality Lit #349

The AQM4 meter measures CO2 levels, CO levels, air temperature, dew point, wet bulb temperature, and humidity. The AQM4 is an ideal instrument for (IAQ) diagnosis. The portable AQM4 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.

Poor indoor air quality causes tiredness, inability to concentrate, and even illness

(ex. ). IAQ monitoring and surveying especially for CO2 levels and air ventilation It is also recommended for regulating standards of industrial air quality in some countries.
