The Extech CO250 air quality meter can measure carbon dioxide (CO2), temperature, humidity, dew point and wet bulb. The Extech CO250 air quality meter also features data logging capabilities and can calculate statistical weighted averages of TWA (8 hour time weighted average) and STEL (15 minute short term exposure limit). The Extech CO250 air quality meter checks for CO2 concentrations using a maintenance free NDIR (non-dispersive infrared) CO2 sensor. Other features of the Extech CO250 air quality meter include a user programmable audible alarm, backlit triple LCD display, built-in RS232 interface for capturing readings onto your PC, data acquisition software and cable (included) to record and document CO2, humidity and temperature data.
