Carbon Emissions Greenhouse Gas Online Monitoring System CEMS For CH4 CO2 N2O
>>Overview
The system employs mature infrared spectroscopy, laser, and electrochemical technologies to achieve real-time, precise, and automated greenhouse gas emission accounting. Compared to material balance-based carbon emission data, the system utilizes real-time monitoring data to establish a greenhouse gas emission accounting methodology system based on monitoring data, further improving the accuracy and real-time nature of carbon emission accounting data. This system can be used for greenhouse gas monitoring in highway service areas, industrial parks, enterprises, and the transportation sector. It can directly measure volatile gases in harsh environments such as factory boundaries and chimney outlets, featuring high precision, good reliability, minimal maintenance, and low operating costs.
>>Features
● 8-inch touchscreen LCD digital display with convenient button or remote control operation.
● The transmitter supports multi-point upload functionality, enabling integrated data collection, analysis, reporting, and publishing.
● Rapid response time with T90 as fast as 10 seconds.
● Equipped with passive relay contact output and audible-visual alarm functions.
● Special high-temperature-resistant light source that solves the issue of damage to ordinary blackbody light sources when measuring gases like CO and CH4, ensuring extremely high reliability.
● Excellent front-end preprocessing system that dries and filters detected gases to ensure more precise detection, stable operation, and extended sensor lifespan.
● White cell with an effective optical path of up to 5.6 meters, enabling low-concentration gas detection.
● Highly sensitive thermoelectric-cooled lead selenide detector for gas detection with high sensitivity.
● Historical data storage function allows for easy viewing of alarm data and records.
● Standard HJ212 protocol enables seamless connection with regional environmental protection platforms.
● Simple installation, minimal maintenance workload, low power consumption, and cost-effective operation.
