Description
Overview
GAOTek portable air quality tester is an instrument for monitoring six pollutant parameters including PM 2.5, PM 10, CO, SO2, NO2 and O3, as well as air temperature and relative humidity. The main function is to monitor the conventional pollution factors in the air for 24 hrs continuous online addition, hydrogen sulfide, volatile organic pollutants, total suspended particulate matter and other meteorological sensors (wind speed, wind direction, atmospheric pressure, rainfall, solar radiation) can be optional.
