The UEi Air Quality Meter AQM4 is an ideal instrument for indoor air quality (IAQ) diagnostics which includes measuring CO2 and CO levels, air temperature, dew point, wet bulb temperature, and humidity. Poor indoor air quality causes tiredness, inability to concentrate, and even illnesses such as Sick Building Syndrome. The portable AQM4 is based on the nondispersive infrared (NDIR) technology for CO2 measurement that is useful for verifying HVAC systems performance and air ventilation control. The meter features a large LCD display, a housing designed to help air ventilation for quick and accurate response, and a mini USB to PC download function for analysis.

Applications include: Public Offices, Classrooms, Factories, Hospitals, and Hotels.
