Equipment introduction SKA/NE-VOC-EX is an explosion-proof VOC online monitoring instrument produced by Shenzhen Shengkaian Technology Co., Ltd., mainly used for monitoring the concentration of gas emitted from unorganized emissions in factories, workshops, and industrial parks. Considering the particularity of the factory boundary environment, the detection of five meteorological parameters such as wind direction, wind speed, temperature, humidity, and air pressure has been added. It can be equipped with DTU or environmental data acquisition instruments, and can be connected to environmental protection platforms and cloud platforms. Realize remote network monitoring by connecting the cloud data of the monitoring instrument, and the transmission is not limited by distance. Establish a boundary data monitoring and analysis system to further improve the processing and management capabilities of boundary air pollution monitoring data, and provide decision-making basis for environmental planning and evaluation 3.
