New 4-IN-1 Thermometer and Hygrometer for PM2.5 & AQI only as it considered the most hazardous pollutant to human health due to its tiny sizes can be inhaled and absorbed.
Temtop 3rd generation laser particle sensor combined with a unique particle swarm optimization algorithm makes particle measurement more accurate and stable.
Touch screen and backlight give clear readings on particle pollutants and their relative AQI level.
