CO2 Infrared Air Quality Monitor Temperature and Humidity Sensor PG- L28A - CO2 ZN-AZ- GG01 Feature:1. Concentration display with flashing light: real-time display of carbon dioxide concentration values per cubic meter, flashing light to display the interval level2. Infrared air quality detection: using infrared sensing technology, which can determine air quality problems more accurately, very practical3. Auto-detecting: Press and hold the power button for 3 seconds to turn on or off, and the surrounding environment can be automatically detected when powered on4. Fast detection with stable value: small size with large function, 1S for real-time refresh time, fast detection can get a relatively stable measurement value5. For planting and laboratory: widely used in agricultural planting, greenhouse planting, production warehouse, material processing laboratory, family, etc. Specification:Item Type: CO2 DetectorModel: PG-L28A-CO2Material: ABS Material: 3.7V 1200mAh Lithium Battery (Built-in)Application: Widely used in agricultural planting, greenhouse planting, production warehouses, material processing laboratories, families, etc. Basic Parameters:CO2 Detection Range: 400 - 5000PPMCO2 Detection Accuracy: 1PPMHo Detection Range: 0 - 0.6mg/TVOC Detection Range: 0 - 2.0mg/Temperature Detection Range: 0 - 50 Temperature Detection Accuracy: 1 C Humidity Detection Range: 0% - 99% RHDurn Detection Accuracy: 5% RHLast Packing:1 x Detector1 x USB Data Cable1 x User ManualHow to Use:Automatically detects at startup.
