HCD6818 Air Quality Transmitter
（T+RH+PM2.5/10++CO+SO2+NO2+O3）
OVERVIEW
HCD6818 is designed and produced by Handan Yunnong Intelligent Agricultural Technology Co., Ltd and usded to measure various meteorological parameter for Smart environment, smart city, industrial pollution. It innovatively realizes PM2.5、PM10、CO、SO2、NO2、O3、T、RH through a highly integrated structure, which can realize the 24-hour continuous online monitoring of outdoor meteorological parameters, and output the parameters to the EPA.In addition, it also can added to measure H₂S, volatile organic pollutants, total suspended particulate matter and other meteorological sensors (wind speed, wind direction, atmospheric pressure, rainfall, sunshine radiation)
APPLICATION
HCD6818 can be widely used in urban environmental monitoring, wind power generation, meteorological monitoring, Bridges, tunnels, ships, aviation airports, agricultural meteorology, water conservancy meteorology, power environment, highway meteorological monitoring and other fields.No maintenance and on-site calibration is required.
