Description It is a quality air quality detector, using a superior electrochemical detection module, with high accuracy, stable performance, can accurately detect carbon dioxide value. Large screen design, you can see the measurement data clearly. Different colors display different air quality. You can have a try.Features:Intelligent carbon dioxide value tester uses air semiconductor-sensor to monitor temperature and humidity of air quality.Adopts superior electrochemical detection module, with high accuracy, stable performance, can accurately detect carbon dioxide value.Strong anti-interference ability, low consumption and long service life.The product does not need calibration, it can be tested after booting, and it can accurately detect carbon dioxide.Different colors corresponding to different air quality, suitable for office, family, and other occasions.Hundreds of ventilation holes at the back of housing not only accelerate the convection between the air and the machine, thereby realizing effective detection, but also provide a fine heat dissipation effect.Widely applications: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, etc.There are 4 types for you to choose, you can choose 3in1 white, 3in1 black, 5in1 white, 5in1 black according to your demands.3in1: The large screen displays the power, CO2 value, temperature and humidity.5in1: The large screen displays the power, CO2 value, TVOC value, HCHO value, temperature and humidity.Note:The new machine needs to be ventilated for 24 hours to ensures accurately measurement,and the product will work normally.Specifications:Name: Air Quality DetectorType: 5in1black, 3in1 black, 5in1 white, 3in1 white (optional)Battery: 1 * 3.7V, 2000mAh lithium battery (included)3in1:CO2 Detection-Range: 400-5000 PPM, +50 +5%PPMCO2 Detection Sensitivity: 1PPMTemp Measurement-Range: 0 to 50 Temp Measurement Accuracy: 1Humidity Measurement-Range: 0%-99%RHHumidity Measurement Accuracy: 2%RH5in1:CO2 Detection-Range: 400-5000 PPM, +50 +5%PPMCO2 Detection Sensitivity: 1PPMTVOC Detection-Range: 0-2.0 mg/mHCHO Detection-Range: 0-0.6 ma/mTemp Measurement-Range: -10 to 50 Temp Measurement Accuracy: 1Humidity Measurement-Range: 0%-99%RHHumidity Measurement Accuracy: 2%RHItem Size: 90 * 70 * 40mm / 3.54 * 2.76 * 1.57inPackage Size: 138 * 95 * 47mm / 5.43 * 3.74 * 1.85inPackage Weight: 150g / 5.29ouncePacking List:1 * Air Quality Detector1 * Cable1 * User ManualOur products are made with the highest quality materials and are designed to provide you with the best possible user experience.
