77535_CD_ADAPTOR High Accuracy CO2, RH & Temp Real-Time Monitor Kit Set w/PC Software Recording Analyzer, Portable Indoor Air Quality Carbon Dioxide Meter Sensor, Temperature/Dew Point/Wet Bulb/Humidity CO2 (Carbon Dioxide) Meters ±1%°C between 5~50°C(41~122°F)This meter measures CO2 level, Air Temperature, Dew Point (DP), Wet Bulb Temperature (WB) and Humidity (RH) and is an ideal instrument for Indoor Air Quality (IAQ) diagnosis. Poor indoor air quality is considered unhealthy because it causes tiredness, loss of ability to concentrate, and even illness (ex. Sick Building Syndrome). IAQ monitoring and survey, especially on CO2 level and air ventilation become widely applied in public areas such as
