This CO2 monitor is a desktop type unit designed for fast and accurate measurement of CO2 level, air temperature and humidity. Equipped with a triple LCD Display and programmable alarms complete with real time clock and calendar. It has a large LCD display and 15° tilt angle for easy reading. In addition, it has ABC (Automatic Baseline Calibration) and Manual Calibration option.

The built-in Non-Dispersive InfraRed (NDIR) sensor provides long term stable monitoring. User can set 2 alarm limits: upper & lower limit. It has an audible & visual alarm to give warning when CO2 concentration exceeds the limit. Once CO2 level goes back to normal the alarm will automatically stop, alarm can be also be stop by pressing any key.

Poor indoor air quality in rooms can lead to fatigue, 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, hotels.

Get quick evaluation of air exchanges rates with the ideal instrument for indoor air quality (IAQ) diagnosis!!!
