Description Multifunctional 5 in 1 CO2 Carbon Dioxide Tester Digital Air Quality TVOC Sensor Meter Temperature Humidity Monitor Gas Analyzer Detector Feature: Carbon dioxide detector: intelligent carbon dioxide value tester. The gas analyzer adopts semiconductor TVOC sensor to monitor air quality, temperature and humidity, and the content of carbon dioxide, formaldehyde and volatile substances in the air It is a high-quality air quality detector, which adopts high-quality electrochemical detection module, with good precision, stable performance, strong anti-interference ability and low consumption, Long service life. Accurately detect carbon dioxide. The large screen displays power, CO2, temperature and humidity. Special high-quality electrochemical detection module is adopted, which has good precision, stable performance, strong anti-interference ability and low consumption The product can be tested without calibration and can accurately detect carbon dioxide. The large screen displays power, CO2 value, temperature and humidity, formaldehyde and volatile matter content Equipped with large screen, different font colors show different air quality Hundreds of vents not only accelerate the convection between air and machine, so as to realize effective detection, but also provide good heat diipation effect Specification: CO2 measurement range: 400-5000ppm CO2 measurement accuracy: 150ppm Temperature measurement range: 0-50 C Temperature measurement accuracy: 1 C Humidity measurement range: 0% - 99% RH Humidity measurement accuracy: 2% RH Screen size: 2.8 inch Screen type: Code Breaking screen Material: ABS Reaction time: 1s Working voltage: 5V / 1A adapter charging (type-C interface) Maximum power: charging current 600mA 3.7V lithium battery power supply Battery capacity: 1200mAh Battery type: lithium battery Charging mode: USB Charging time: 1 hour Size: 92 * 72 * 37mm/3.6x2.8x1.5in Color: Black/White 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.
