Description: It is an air quality tester that uses an excellent electrochemical detection module with high accuracy and stable performance, and can accurately detect carbon dioxide values. Large screen design, measurement data is clear at a glance. Different colors represent different air quality. Features: The intelligent carbon dioxide value tester uses air semiconductor sensors to monitor air quality, temperature and humidity.The superior electrochemical detection module is adopted, with high accuracy and stable performance, which can accurately detect carbon dioxide value.Strong anti-interference ability, low power consumption and long service life.The product does not need to be calibrated, it can be detected when it is turned on, and it can accurately detect carbon dioxide.Different colors correspond to different air quality, suitable for offices, homes and other occasions.Hundreds of ventilation holes on the back of the case can not only accelerate the convection between the air and the machine for effective detection, but also provide good heat dissipation.Widely used: agricultural planting, greenhouse vegetables, production warehouses, material processing, home interior decoration, etc. Specification: Name: Air Quality MonitorColor: black, white, (optional)Battery: 1*3.7v, 2000mah lithium battery (included)5 in 1: Large screen displays power, CO2 value, TVOC value, HCHO value, temperature and humidity.Co2-Scale detection: 100-5000ppm, +50 + 5% ppm CO2 detectionSensitivity: 1ppmTVOC-Scale detection: 0-2.0 mg/m3;HCHO-scale detection: 0-0.6 ma/m3;Temperature measurement range: -10 to 50 ??CTemperature measurement accuracy: ?? 1 ??Humidity measurement range: 0%-99% RHHumidity measurement accuracy: 2% RHItem Dimensions: 90 x 70 x 35mm / 3.5 x 2.8 x 1.4in.Product weight: 129gPackage size: 11.5.0 x 11.5 x 4.5cmPacking weight: 191g Package included: 1 x Carbon Dioxide Tester1 x USB cable1 x English User Manual
