Indoor Air Quality Meter measures CO2, air temp, RH, and more.

Press Release Summary:

Leveraging NDIR (non-dispersive infrared) technology, 800046 can be used to monitor IAQ in spaces as well as test air from HVAC equipment. Backlit simultaneous display shows CO2 level from 0–5,000 ppm, humidity from 0–100%, and air temperature from 14 to 140°F. User can also choose rotating display of dew point (8 to 140°F) and wet bulb temperature (-100 to 140°F) instead of air temperature. Additional calculations cover TWC (Time Weighted Average) and STEL (Short-Term Exposure Limit).

Original Press Release:

Indoor Air Quality Meter - 800046

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 TWC (Time Weighted Average) and STEL (Short-Term Exposure Limit).  Simple user calibration of CO2 and RH.  Features audible CO2 threshold alarms, min/max/ave, hold and a computer interface.  NDIR (non-dispersive infrared) technology ensures long-term accuracy, stability and reliability.  Comes in a hard carrying case with 4 “AA” batteries.
