18-in-1 Air Quality Analyzer: CO2, TVOCs, HCHO, PM2.5, PM10, temperature, humidity. Battery-powered indoor tester. Data storage.

Features:1.Measuring Device: The air quality meter uses semiconductor and infrared technology to accurately measure the air quality index, CO2, HCHO, TVOC, PM5.0, PM0.3, PM1.0, PM2.5, PM10, display data curves, compare particle values, store data (which can be imported to a computer), as well as temperature and humidity.
2.Type-C Charging: The 18-in-1 air quality meter has a built-in 2000mAh battery, which can operate continuously for 7 hours.Has a Type-C charging port for easy charging via USB power.
3. 2.8-inch screen for easy reading: This home air quality tester features a 2.8-inch HD screen that displays 13 real-time data points, with different colors indicating air quality status for easy reading.
4.Accurate and sensitive: The indoor air quality meter is equipped with highly sensitive sensors that provide accurate readings of CO2 (1 ppm), TVOC (0.01 mg/m³), HCHO (0.01 mg/m³), and PM (1 μg/m³)
5.Data storage: The air quality tester can record the ratio of PM0.3, PM0.5, PM1.0, and PM2.5 particles before and after 1 minute; you can press the button to display the data curve for PM2.5, HCHO, TVOC, and CO2, and compare the particle data.Can be connected to a computer to retrieve data records, can save up to one year of data, overwriting the previous record over time.
