Multi-function Air Monitor Digital Display CO2 HCHO TVOC Detector CO2 Carbon Dioxide Meter Air Quality Monitor Gas Detector

Carbon dioxide detector: smart carbon dioxide value tester gas analyzer uses semiconductor TVOC sensor, air quality monitoring temperature and humidity. It is a high-quality air quality detector, using a good-quality electro detection module, with good accuracy, stable performance, low consumption and long service life. Accurately detect carbon dioxide. The large screen displays power, CO2, temperature and humidity. The electro detection module of good quality is adopted, with good accuracy, stable performance, low power consumption and long cabinet life. The product does not need calibration, it can be tested after booting, and it can accurately detect carbon dioxide. The large screen displays power, CO2 value, temperature and humidity. Equipped with a large screen, different horizontal bar colors display different air quality, 400-800ppm: green is normal, 800-1800ppm: yellow concentration is slightly higher, greater than 1800ppm: red horizontal bar concentration will be displayed super high, and an audible alarm will sound The alarm sound stops after 10 seconds. Hundreds of ventilation holes at the rear not only accelerate the convection between the air and the machine, thereby realizing effective detection, but also provide good heat diipation efficiency.
