HT-2000 USB Digital CO2 Monitor Meter LCD Exhaust gas analyzer Detector CO2 Analyzers Bullet Point: It's used for measuring Carbon Dioxide concentration, temperature, humidity, dew point temperature and wet bulb temperature Too much Carbon Dioxide indoor will easy cause tired, not concentration, even cause sick building syndrom. A good indoor environment will be benifit to body health and also improve body immunity, reduce the disease rate Carbon dioxide meter also has important function in agriculture, such as vegetable greenhouse Carbon Dioxide Meter is widely used in factory, workshop, green house, clean room, industry and agriculture, wine bar, hotel, hospital, shop market, airport, railway station, entertainment hall and movie theater etc.,
