Monitor indoor air quality in public spaces with potentially high levels of CO₂ (carbon dioxide)

Poor air quality may cause tiredness, inability to concentrate, and even illness (i.e., sick building syndrome). This instrument is ideal for monitoring indoor air quality in crowded public spaces with potentially high levels of CO₂ (carbon dioxide) such as offices, factories, classrooms, hospitals, and hotels. The same measurement parameters can also be used to test air from HVAC equipment. The unit provides backlit simultaneous display of CO₂ level, humidity, and air temperature, or the user may choose a rotating display of dew point and wet bulb temperature instead of air temperature. It also calculates TWA (Time Weighted Average) and STEL (Short-Term Exposure Limit). Simple user calibration of CO₂ and RH. Features audible CO₂ threshold alarms, min./max./avg., hold, and a computer interface. NDIR (non-dispersive infrared) technology ensures long-term accuracy, stability, and reliability.

Meter measures CO₂, humidity, dew point, air temperature, and wetbulb temperature.
