This 3-in-1 CO2 datalogger & monitor is designed for fast & accurate measurement & logging of CO2 level, air temperature and humidity. It display 3 parameters 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.
