Description 5 in 1 Portable Digital Carbon Dioxide USB Charging Multifunctional Air HCHO Detector Gas Analyzer Temperature Humidity Quality Monitor Tools Feature: 1. Carbon dioxide detector: intelligent carbon dioxide value tester, gas analyzer, using the air semiconductor TVOC sensor, air quality temperature and humidity, air carbon dioxide, formaldehyde and volatile substances content monitoring. 2. It is a high-quality air quality detector, using good quality electrochemical detection module, good precision, stable performance, strong anti-interference ability, low consumption. 3. Long service life and accurate detection of CO2. 4. Adopt good quality electrochemical detection module with good precision, stable performance, strong anti-interference ability and low consumption. 5. The product does not need calibration, it can be tested by turning on the power and detects CO2 accurately. 6. Large screen to display power, CO2 value, temperature and humidity. 7. Equipped with a large screen, different font colors show different air quality, green 400-450ppm, blue 451-700ppm, purple 701-1000ppm, yellow 1001-2000ppm, red 2001-5000ppm. 8. Hundreds of ventilation holes at the back not only accelerate the convection between the air and the machine, thus achieving effective detection, but also provide good heat diipation.
