Description
Monitor Indoor Air Quality (IAQ) 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. 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. 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. In order to connect this model to a computer to stream data, you will need the USB Cable 840054 and Data Acquisition Software 840052. Comes in a hard carrying case with 4 AA batteries. Uses optional AC Adapter (840027).- CO2
