DM73A 4.3 Inch TFT LED Digital Screen Portable Laser PM2.5 PM1.0 PM10 Temperature Humidity HCHO TOVC AQI Detector Intelligent Multifunction Detect Tool ( Item#: E13623 )

This product is a multifunctional air quality monitor that detects Formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC), Particulate Matter <2.5 micron#31;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 formalde-hyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.

Features:
This detector is suitable for indoor and outdoor air quality, muti-envornmental air quality monitoring for furniture, decorations, cars, and so on.
4.3 inch LCD display, 480*270 pixels, simple and elegant, with high test accurancy, stable performance, with clear and easy to understand digital display, let you know the current air quality at a glance.
