Feature:1. 9in1 Air Quality Tester: This detector can be used to test and display the concentration of PM2.5, PM10, CO, CO2, TVOC, HCHO, AQI, temperature and humidity at the same time.2. High Accurate Sensors: Uses high-precise semiconductor TVOC sensor, electrochemical CO sensor, infrared PM2.5 sensor, temperature and humidity sensor, with high sensitivity, superior interference resistance ability, stable working performance, with low power consumption.3. TFT Color Display: This air quality monitor with a large TFT color display, you can the data is clearly visible and the screen is not dazzling.4. Cellphone Tuya APP Control (Wifi Version Only): Search for Tuya APP in the application program, the device will enter the pairing state after the firsttime opening, and you can view the specific data on the APP after completing the connection. (Because it takes time to upload data, it is normal for the APP data to deviate from the real-time data of the detector.)5. AQI Air Quality Level Indication Function: Equipped with air quality level division function, use different color to show the different quality of the air being monitored, allowing you to more accurately and more visual know the current air conditions.6. Strong Heat Dissipation: Hundreds of ventilation holes reserved on the housing not only accelerate the convection between the air and the machine, thereby realizing effective detection, but also provide a fine heat dissipation effect.7. Wide Applications: Real-time detection, automatic refresh data, with multi-use. Suitable for agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, business offices, and etc.Specification:This detector has TFT color display, which can be used to test and display the concentration of PM2.5, PM10, CO, CO2, TVOC, HCHO, AQI, temperature and humidity at the same time.
