It is a high-quality air quality detector, using superior electrochemical detection module, high accuracy, stable performance, can accurately detect carbon dioxide value. The large screen design makes the measurement data clear at a glance. Different colors represent different air quality. You can try.feature:The intelligent carbon dioxide value tester uses an air semiconductor sensor to monitor the temperature and humidity of the air quality.Adopting superior electrochemical detection module, with high accuracy and stable performance, it 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 tested after starting up, 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 casing can not only accelerate the convection between the air and the machine, thereby realizing effective detection, but also provide good heat dissipation effects.Widely used: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior decoration, etc.There are 4 types for you to choose, you can choose 3 in 1 white, 3 in 1 black, 5 in 1 white, 5 in 1 black according to your needs.Three in one: Large screen displays power, CO2 value, temperature and humidity.5in1: Large screen displays power, CO2 value, TVOC value, HCHO value, temperature and humidity.Specification:Name: Air Quality DetectorType: 5 in 1 black, 3 in 1 black, 5 in 1 white, 3 in 1 white (optional)Battery: 1*3.7V, 2000mAh lithium battery (included)triple:CO2 detection range: 100-5000 PPM, +50 +5%PPMCO2 detection sensitivity: 1PPMTemperature measurement range: -10 to 50 Temperature measurement accuracy: 1Humidity measurement range: 0%-99%RHHumidity measurement accuracy: 2%RHFive in one:CO2 detection range: 100-5000 PPM, +50 +5%PPMCO2 detection sensitivity: 1PPMTVOC detection range: 0-2.0 mg/m3;HCHO detection range: 0-0.6 ma/m3;Temperature measurement range: -10 to 50 Temperature measurement accuracy: 1Humidity measurement range: 0%-99%RHHumidity measurement accuracy: 2%RHItem size: 90 * 70 * 40mm / 3.54 * 2.76 * 1.57inPacking size: 138*95*47mm/5.43*3.74*1.85inPackage weight: 150 grams / 5.29 ouncesPacking list:1 * Air quality detector1 * cable1 * User Manual
