All-in-one meter measures CO2, humidity, dew point, plus air and wet bulb temperatures.Your students can investigate air quality in the classroom, laboratory, or other indoor space with this portable meter. Backlit display indicates CO2 level, humidity, and air temperature, or choose a rotating display of dew point and wet bulb temperature instead of air temperature. Meter calculates TWA (time-weighted average) and STEL (short-term exposure limit) for CO2 measurements.Additional features include audible CO2 threshold alarms; hold, min, max, and avg functions; an RS232 computer interface; and simple user calibration. NDIR (nondispersive infrared) CO2 sensor technology ensures long-term accuracy, stability, and reliability. Meter comes in a hard carrying case with 4 AA batteries.Note:Relative humidity calibration solutions are not included and must be purchased separately.
