Feature:1. Detection Range: The meter's CO2 detection range is 400 to 5000PPM, CO2 detection accuracy is 5PPM, TVOC detection range is 0 to 2PPM.2. Realtime Reading: The CO2 detector can display the CO2 concentration value per cubic meter in realtime, and the flashing light shows the level of the zone it belongs to.3. HD Screen: Our CO2 temperature humidity meter has a high resolution screen with automatic brightness adjustment.4. Color Indicator Below Number: CO2 temperature humidity meter has a color indicator below the number of each indicator, so the data can be understood at a glance.5. Rapid Response: High sensitivity, excellent internal sensors, with multi mode compensation algorithm, accurate and reliable measurement data. Ventilation port design allows full contact between air and sensor, thus improving efficiency.Specification:Item Type: Carbon Dioxide DetectorMaterial: ABSModel: XY T02Battery: 3.7V lithium battery 1200mAh (built in battery shipping)Uses: Widely used in agricultural planting, greenhouse planting, production warehouses, material processing laboratories, families, etc.Basic ParametersCO2 Detection Range: 400-5000PPMCO2 Detection Accuracy: 5PPMTVOC Detection Range: 0-2PPMTemperature Detection Range: 0-50Temperature Detection Accuracy: 1Humidity Detection Range: 0% - 99%RHHumidity Detection Accuracy: 2%RH.Package List:1 x Carbon Dioxide Detector1 x USB Data Cable1 x Instruction ManualNote:This product cannot measure formaldehyde.
