Meter Air Quality Indoor

Monitor indoor air quality in public spaces with potentially high levels of CO₂ (carbon dioxide) CO,sub Humidity Dew Point Air Temperature Wet Bulb Temperature 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/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. Dim: 8½ × 2½" (210 × 75 × 65mm). Weight: 10oz (280g).
