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.
