Type-c charging design: Type-c charging port, built-in 2000mah rechargeable lithium battery, supports usb connection for use.6.9 tests: Equipped with high-precision sensors, it can quickly and efficiently identify co2, co, hcho, tvoc, c6h6, aqi, noise, temperature and humidity in the air, with comprehensive functions.Parameters: Product name: noise air quality detector (semiconductor sensor)Material: absWorking voltage: 3.7vWorking current: 260maCo2/co resolution: 1ppmNoise resolution: 1dbCharging method: type-c interface/dc5v/1aBattery capacity: 2000mah lithium batteryMeasurement objects: temperature, humidity, noise co、co2、 hcho、 tvoc、c6h6、aqiProduct size: 90 * 70 * 35mmPrecautions1. The noise meter does not have an alarm sound, which will interfere with the operation of the noise meter, so the noise function can only look at numbers and there is no alarm sound2. In general, there is no co in daily life. This is carbon monoxide gas. When carbon is burned in a closed room or coal is not completely burned, co is producedOperating instructions1. Press the power button to turn on/off. (start detection 60 seconds after startup)2. Short press the power button once to switch temperature units. 3. Short press the power button twice to turn off/on the sound.4. Press the power button three times to manually calibrate tvoc. 5. Short press the power button 4 times to turn off the screen (during device operation).6. Built in rechargeable lithium batteryPackage include:Detector * 1Instruction manual * 1Usb-c charging cable * 1
