UEI Data Logging AQM4 Indoor Air Quality Meter measures Carbon Monoxide, Carbon Dioxide, Temperature and Relative Humidity
The AQM4 meter measures CO² levels, CO levels, air temperature, dew point,
wet bulb temperature, and humidity. The AQM4 is an ideal instrument for indoor
air quality (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
Poor indoor air quality causes tiredness, inability to
concentrate, and even illness (ex. Sick Building Syndrome). IAQ monitoring and
surveying especially for CO² levels and air ventilation has become widely
applied in public offices, classrooms, factories, hospitals, and hotels. It is
also recommended for regulating standards of industrial air quality in some
