Temtop LKC-1000S+ Air Quality Monitor 9-IN-1 Data Histogram

Features: The latest 9-IN-1 air quality detector measures PM2.5, PM10, particles, HCHO(formaldehyde), TVOC, AQI, temperature, humidity and histogram function. The new histogram function shows the changes of PM2.5 for the last 12 hours. Temtop advanced third-generation laser particle sensor has a lifetime up to 20,000 hours. Combined with the unique particle swarm optimization algorithm, it makes particle measurement more accurate and stable. The pre-calibrated electrochemical sensors will accurately capture formaldehyde molecules accompanied by the detection function covering a wide range of organic pollutants. Large TFT screen display make it clear and easy for data viewing and  battery light indicator helps you to check on battery at any time Product Specifications:● Name: Laser particle multi-functional detector● Model: LKC-1000E/1000S/1000S+( refer to appendix for specific functions)● Display mode: TFT color LCD screen● Battery voltage: 3.7VDC● Overall dimension: 177*65.5*32● Pow
