7755 Digital CO2 Carbon Dioxide Temperature RH Humidity DP WB NDIR Sensor Indoor Air Quality 9999ppm USB Monitor LoggerPoor 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 offices, classrooms, factories, hospitals, and hotels. This meter measures CO2 level, Air Temperature, Dew Point (DP), Wet Bulb Temperature (WB) and Humidity (RH) and is an ideal
