Description
Overview
GAOTek negative ions air quality tester is a multifunctional air quality monitor that detects Carbon dioxide (CO2), Formaldehyde (HCHO). Total Volatile Organic Compounds (TVOC), Particulate Matter <2.5 micron-sized particles (PM 2.5 PM 1.0 PM 10), Temperature, and Humidity with clock and record function. It combines multiple air sensors with a built-in fan to allow real-time monitoring of Carbon dioxide (CO2), formalde- hyde (HCHO), total volatile organic compounds (TVOC), temperature, and humidity on its digital LCD display.
