MEASUREMENT OBJECT: The air quality meter uses semiconductor and infrared technology to accurately measure Air Quality Index, CO2, HCHO, TVOC, PM5.0, PM0.3, PM1.0, PM2.5, PM10, data curve display, particulate value comparison, data storage(can be imported into a computer), as well as temperature and humidity<br/>2. TYPE C CHARGING: 18 in 1 air quality meter built in 2000mAh battery, can run continuously for 7 hours. Has a Type C charging port for easy charging via USB power<br/>3. 2.8IN SCREEN FOR EASY READING: This home air quality tester features a 2.8in HD screen that displays 13 data points in real time, with different colors indicating air quality status for easy reading<br/>4. ACCURATE AND SENSITIVE: The indoor air quality meter is equipped with highly sensitive sensors that provide accurate readings of CO2 (1PPM), TVOC (0.01mg/m³), HCHO (0.01mg/m³) and PM (1μg/m³)<br/>5. DATA STORAGE: Air quality tester can record the ratio of PM0.3, 0.5, 1.0 and 2.5 particles before and after 1 minute; You can press the key to view the data curve of PM2.5, HCHO, TVOC, CO2, and compare the data of particulate matter. Can be connected to the computer to extract data records, can save up to one year of data, time will overwrite the previous record<p><br/></p><p><b>Specification:</b></p>Item Type: Air Quality Meter<br/>Temperature Range: 0-70℃<br/>Display: LCD screen and backlight <br/>Operating Voltage: DC5V 1A TYPE C USB <br/>Operating Current: 180mA<br/>Sensors: PM2.5 infrared sensor, semiconductor sensor <br/>Battery: 1 x 3.7V rechargeable li ion battery 2000mAh<br/>Size: Approx. 90 x 70 x 35mm / 3.54 x 2.76 x 1.38in<br/>Operating Current: 260mA<br/>Material: ABS<br/><p><br/></p><p><b>How to Use:</b></p>1. Single click on the main interface to switch between Celsius and Fahrenheit. <br/>2. Double click to turn on or off the sound. <br/>3. Triple click to enter the calibration interface. <br/>4. Quadruple click to enter the screen off mode (single click to turn on the screen in screen off mode). <br/>5. Quintuple click to enter the curve interface (single click to switch in the curve interface, quintuple click to return to the main interface). <br/>6. Sextuple click to enter the PM2.5 comparison interface (double click to record the first group of 30-second evaluation data, double click again to record the average data of 2 groups of 30 seconds, quintuple click to return to the main interface). <br/>7. Septuple click to enter the temperature adjustment interface (single click to increase by 1 degree Celsius, double click to decrease by 1 degree Celsius, quintuple click to exit or exit the interface after five seconds of inactivity).<p><br/></p><p><b>Package List:</b></p><p>1 x Air Quality Meter<br/>1 x USB Cable<br/>1 x User Manual</p></div><br/><p><br/><br/><br/><br/><br/><br/><br/><br/><br/></p></div></div></div>
