VOCs emission monitoring system

The implementation of the portable hydrogen flame ionization detector method for the determination of fixed pollution source exhaust gas/total hydrocarbons/non total hydrocarbons has eliminated the previous gap in on-site monitoring of fixed pollution sources, total hydrocarbons, and non total hydrocarbons. This enables early monitoring of NMHC emissions and makes remediation more convenient. In addition, this method can also provide technical support for the acceptance and comparison of online NMHC monitoring instruments. The release of the "Technical Specification for Monitoring Volatile Organic Compounds in Fixed Pollution Source Waste Gas" aims to, on the one hand, sort out existing analyses, integrate and standardize the control and technical requirements of each monitoring link; On the other hand, by applying and promoting mature and advanced VOCs monitoring technologies, the current requirements for strengthening VOCs pollution sources have been strengthened, and an important link in building a standardized organic matter monitoring system has been improved, providing strong behind the scenes support for VOCs governance.

VOC online monitoring mainly consists of three parts: LED display screen for real-time monitoring and understanding of the situation; The cloud platform data display platform can be combined with electronic maps to intuitively understand the location of each device and view the real-time monitoring factors collected by the sensors equipped on the device. The data display also supports various forms such as line charts, making it convenient for users to view the data and trends of each monitoring factor during each time period, and compare the parameters between monitoring points for data analysis; The video surveillance fusion display displays the on-site parameters in character form on the video surveillance screen and can be stored together with the video to prevent tampering.

Jinye Instrument Shandong Co., Ltd. mainly provides customized development services for dust and noise monitoring systems, TVOC online monitoring systems, micro air quality monitoring stations, odor gas online monitoring systems, negative oxygen ion monitoring stations, micro meteorological monitoring stations, catering fume monitoring, networking platforms, IoT terminals, and sensor platforms. The company's products comply with relevant government standards and can be connected to regulatory platforms of provincial and municipal governments, as well as subordinate units across the country. They can be used normally under various harsh weather conditions outdoors, and users have no worries about purchasing.
