5 in 1 Portable CO2 Meter Temperature Humidity Sensor Tester Air Quality Monitor Analyzer Carbon Dioxide Gas TVOC HCHO Detector
Feature:
Carbon dioxide detector: Smart carbon dioxide value tester gas analyzer uses air semiconductor TVOC sensor to monitor temperature and humidity of air quality, the content of carbon dioxide, formaldehyde and volatile substances in the air.
It is a high-quality air quality detector, using a good-quality electrochemical detection module, with good accuracy, stable performance, strong anti-interference ability, low consumption and long service life. Accurately detect carbon dioxide. The large screen displays power, CO2, temperature and humidity.
The product does not need calibration, it can be tested after booting, and it can accurately detect carbon dioxide.
Equipped with a large screen, different font colors display different air quality, green 400-450ppm, blue 451-700ppm,Purple 701-1000ppm, yellow 1001-2000ppm, red 2001-5000ppm.
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 a good heat dissipation effect.
