3-in1 CO2 Carbon Dioxide Desktop Datalogger Indoor Air Quality Temperature Relative Humidity RH 0~9999ppm Clock EU EU Plug

Description:
AZ7788 3 in 1 CO2 Carbon Dioxide Desktop Datalogger Indoor Air Quality Temperature Relative Humidity RH 0~9999ppm Tester Clock Date Display
This 3-in-1 CO2 datalogger is designed for fast accurate measurement logging of CO2 level, air temperature and humidity. It display 3 paramaters simultaneously together with data time. An ideal instrument for indoor air quality (IAQ) diagnosis and HVAC system performance verification.
This logger is factory pre-calibrated at standard 400ppm CO2 concentration. It has a large LCD display and 15 tilt angle for easy reading and ABC (Automatic Baseline Calibration) and Manual Calibration option. The built-in Non-Dispersive InfraRed (NDIR) sensor provides long term stable monitoring.
It is also suggested in regulations of industrial hygiene in some countries. Poor indoor air quality in rooms can lead to fatigue or tiredness, lack of concentration and illness (Sick Building Syndrome) due to high CO2 concentration.
IAQ monitoring and ventilation surveys of CO2 level air ventilation become widely applied in public areas such as offices, classrooms, factories, hospitals, day care centers and hotels.
