·Analysis method: GC-FID method was used, which was consistent with the reference method HJ38-2017. GC-FID has chromatographic analysis, high detection limit, strong scalability, and scalable characteristic pollutant monitoring.

·Monitoring factor expansion: On the basis of meeting the monitoring of total menstrual, non-methane total menstrual and benzene series, the advantages of customized VOC other characteristic factors monitoring.

·Sampling analysis full heat method: sampling probe, sampling pipeline temperature until the entire analysis process temperature ≥120℃ (can be adjusted according to the actual site and sample conditions), no need to remove water, effectively avoid sample loss, to ensure the accuracy and reliability of monitoring data (in line with HJ1013-2018).

·FID detector use safety design: meet the set conditions of automatic ignition function, flame extinguishment determination, to ensure the safety of hydrogen use. The function of overtemperature alarm for heating components such as injection valve, column box and detector protects key components from damage.

·With automatic remote/near-end calibration function, calibration cycle can be programmed to achieve instrument quality control and fault isolation judgment.

·Built-in integrated industrial computer, HD color LCD touch screen display, the software adopts hierarchical modular design, the operation interface is simple and easy to control. It has operation permission restriction and password control functions to prevent operation errors or unauthorized operations.

·The system software has the functions of automatically recording, storing data and mapping, automatic diagnosis and fault alarm, etc. You can set criteria to query and display historical data and trend charts, and provide a variety of report formats for choice.

·Provide LAN, RS232, RS485, 4-20mA a variety of data transmission modes, in line with the standard Modbus protocol, to achieve real-time data communication, and access to the enterprise monitoring center and environmental protection department monitoring platform.

·Provide customized solutions: If the installation area has explosion-proof requirements, explosion-proof analysis rooms or explosion-proof models can be customized to meet the safety and environmental protection needs.
