Multi-function Air Quality Monitor Digital Display CO CO2 HCHO TVOC Gas Detector Carbon Dioxide Meter Feature: Carbon dioxide detector: Intelligent carbon dioxide value tester. The gas analyzer uses an empty semiconductor TVOC sensor to monitor the temperature and humidity of the air quality. It is a air quality detector, using an 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 the date, time, power, CO2 concentration, temperature and humidity. It adopts the electrochemical detection module of , with good accuracy, stable performance, strong anti-interference ability, low consumption and long life of the cabinet. The product does not need calibration, it can be tested after booting, and it can accurately detect carbon dioxide. Different font colors show different air quality, 400-1000ppm: green flashing, 1001-3000ppm: orange flashing, more than 3000ppm: red flashing, hundreds of ventilation holes in the rear not only accelerate the convection between the air and the machine, so as to achieve Effective detection, but also provides a good heat diipation effect. Specification: Shell material: ABS Product size: 160x90x41mm or 6.3x3.54x1.61 CO2 measurement range: 400-5000ppm CO2 measurement accuracy: 50and5 percent ppm Temperature measurement range: -10-500C Temperature measurement accuracy: 1C Humidity measurement range: 10 percent -99 percent RH Humidity measurement accuracy: 1 percent RH Working environment: 0-50C Battery capacity: 1200mA Charging method: USB Power input: Type-C USB 5V2A Color: White, Black Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you Please allow 1-2cm measuring deviation due to manual measurement. 1 X Carbon Dioxide Detector 1 X USB Cable Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
