Gas Detector Household Indoor High-precision Smog, Dust, Formaldehyde, Air Quality Detector

The multifunctional air quality detector detects dust, formaldehyde, benzene, etc.Independent sensor (dust sensor, formaldehyde electrochemical sensor, TVOC sensor, temperature and humidity sensor)ARM processor, fast calculation speed, more accurate detection.Product SpecificationsDisplay method: 2.8” LCD screen display, 320 x 240 pixelsAtmospheric pressure: 86Kpa - 106KpaDetection method for PM: ScatteringSampling time: 1.5 secondsProduct Size: 164 x 69 x 44 mmDetection temperature: -10°C to 50°C; 14°F to 122°FRelative humidity: 20% - 85%Storage temperature: -10°C to 60°C; 14°F to 140°FConcentration unit for PM (PM2.5/1.0/10) : ug/m³Concentration unit for HCHO and TVOC: mg/m³Power source: Lithium battery with 2000 mAh capacity; 5V DC power charging via micro USB portProduct weight: 183g Product Description<;2.5 micron-sized particles (PM2.5/1.0/10), Temperature, and Humidity with clock and record function. As a scientific air quality detection device, it combines multiple 4 high-precision independent air sensors with a built-in fan to allow real-time monitoring of formaldehyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.<;=0.10 mg/m3(0.08 ppm/m3)<;= 0.6 mg/m3(0.45 ppm/m3)The formaldehyde alarm threshold is 0.1 mg/m3. If levels of HCHO exceed this alarm threshold, the device will alarm with short beeps.(4) About Charging When low battery icon is displayed, the device needs to be charged. Insert the included or another compatible micro USB charging cable into the device. Attach the other end to a USB DC charger (such as a smartphone charger) that outputs DC 5V at >=1000mA. Fully charge for at least 2-3 hours before use. Avoid charging with a USB computer port which only outputs 500mA.(5) Technical Parameter-PM2.5/PM1.0 /PM10 detectionDetection principle: scatter
