Technical Advantages

Highly integrated system design, with an all-in-one structure incorporating industrial computer, chromatograph, dynamic calibrator and pretreatment unit.
Two cabinet options available: standard cabinet and outdoor compact station cabinet, expanding its scope of application.
High stability: core components such as monitoring host and calibrator are self-developed, ensuring reliable measurement stability.
The system adopts EPC technology to control the flow rates of carrier gas, zero gas and hydrogen, featuring high precision and excellent repeatability.
Equipped with a fault self-diagnosis function, which automatically identifies and stores system fault information.
Has a low carrier gas flow alarm function; the system will automatically shut down when the carrier gas supply is insufficient.
Intelligent safety protection design, with functions including automatic ignition, flameout detection, power-off protection, over-temperature protection and status monitoring.
