4.3 Inch Digital LCD Display Multifunctional Thermometer and Hygrometer Air Quality Analyzer ( Item#: E10825 )

This product is a multifunctional air quality detector that detects formaldehyde (HCHO), total volatile organic compounds (TVOC), particulate matter <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 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.

Features:
Laser sensor for PM2.5 to detect dust smog.
Electrochemistry independent sensor for HCHO to detect formaldehyde.
Semiconductor sensor for TVOC to detect benzene, etc volatile organic compounds.
With temperature and humidity sensor.
AQI for integrated air quality index.
Support time and date, self-calibration function.
LCD screen display, 24 hours real time monitoring.
Measurement items: PM2.5, PM1.0, PM10, HCHO, TVOC, temperature, humidity, AQI.
