5in1 CO2 Digital Thermometer Humidity Tester Carbon Dioxide Tvoc Hcho Air Quality Monitor White
Semiconductor sensors are very sensitive to organic gases such as formaldehyde vinegar and oil fume and are susceptible to changes in sensor values due to their influence. Describe: Carbon dioxide detector: Intelligent carbon dioxide value tester gas analyzer uses air semiconductor TVOC sensor to monitor the 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 that uses high-quality electrochemical detection modules. It has the characteristics of good accuracy stable performance strong anti-interference ability low power consumption and long service life. Accurately detect carbon dioxide. The large screen displays power carbon dioxide temperature and humidity. The product does not need to be calibrated it can be tested after starting up and it can accurately detect carbon dioxide. Equipped with a large screen different font colors different air quality green 400-450pm blue 451-700ppm purple 701-1000ppm yellow 1001-2000ppm red 2001-5000ppm. Hundreds of ventilation holes on the back not only accelerate the convection between the air and the machine and realize effective detection but also have a good heat dissipation effect. Specification: Material: ABS Color: Black White Test temperature range: -10℃～70℃ Humidity test: 0-99% Rh Working voltage: 5V/1A adapter charging Use time:
