เครื่องวัดปริมาณก๊าซคาร์บอนไดออกไซด์ในอากาศ Air Quality CO2 Monitor)

(Air Quality CO2 Monitor, 0-2000 ppm)

(Model: CO-87)

ราคาพิเศษ 990 บาท

This 3-in-1 CO2 monitor (desktop type) is designed for fast and accurate measurement of CO2 level, air temperature and humidity. Features a triple LCD Display and 15° tilt angle for easy reading. Also features programmable alarms with real time clock and calendar. In addition, it has ABC (Automatic Baseline Calibration) and Manual Calibration option.

It can be set in 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, but can be also be stop by pressing any key. The built-in Non-Dispersive InfraRed (NDIR) sensor provides long term stable monitoring.

Poor indoor air quality in rooms can lead to fatigue, lack of concentration and illness (Sick Building Syndrome) due to high CO2concentration. IAQ monitoring and ventilation surveys of CO2 level & air ventilation become widely applied in public areas such as offices, classrooms, factories, hospitals, hotels.
