Product details
  • Chinese display, Chinese keyboard input, large LCD blue screen, rich display content, large amount of information, capable of real-time monitoring of various parameters such as temperature and flow rate.


    Automatic monitoring will be implemented for each heating zone, and the heating power will be automatically cut off when the heating zone exceeds the temperature limit.

    The transformer oil (insulation oil) analysis dedicated gas chromatograph is a multifunctional gas chromatograph designed specifically for the analysis of dissolved gas content in insulation oil. The instrument adopts an advanced dual column parallel and series thermal conductivity detector, methane conversion furnace, and dual hydrogen flame detector gas path process, and uses three signal simultaneous output technology to complete the full analysis of dissolved gas components such as H2, CO, CO2, CH4, C2H4, C2H6, C2H2 in insulation oil in one injection. It has powerful functions, excellent performance, good separation effect, high sensitivity, good reproducibility, simple operation, low failure rate, and beautiful appearance. It can fully meet the needs of multi task detection and analysis of insulation oil, and all performance indicators are superior to national standards. The preferred choice for insulation oil analysis users.

  • 1. Chinese display, Chinese keyboard input, large LCD blue screen, rich display content, large amount of information, capable of real-time monitoring of various parameters such as temperature and flow rate.

    2. Automatic monitoring will be implemented for each heating zone, and the heating power will be automatically cut off when the heating zone exceeds the temperature limit.

    3. It has a gas cut-off protection function. When the carrier gas pressure is below 0.1MPa, the instrument will automatically alarm and cut off the heating power supply and thermal bridge current.

    4. It has parameter storage function. After the instrument is turned off, the next time it is turned on, simply turn on the main power switch of the instrument, and the instrument will automatically run in the state before the last shutdown, achieving the true "power on and use" function. Alternatively, when the power is restored after a power failure, the instrument will automatically return to the operating state before the power failure.

    5. It has a fault self diagnosis function, and the instrument detects various operating parameters in real time. When the system encounters abnormalities, the microcomputer system will automatically protect the instrument.

    6. The gas path system adopts a unique pressure stabilization process design, which reduces the impact of pressure fluctuations on the detector during gas injection, thereby minimizing the influence of shock peaks on analysis and ensuring high reproducibility and accuracy of analysis results.

    7. The classic two box design of the whole machine is easy to operate and maintain, making the appearance of the instrument cleaner and more beautiful, and improving the safety of instrument operation.

    8. Pressure gauges are used to indicate the carrier gas, hydrogen gas, and air, making it easy for operators to understand the chromatographic analysis conditions at a glance and operate.

    9. The main and key components are all imported components, which extends the service life of the whole machine and reduces maintenance costs.

    10. The instrument undergoes sufficient debugging before leaving the factory. After arriving at the usage site, users only need to ventilate and turn on the power to use it, making the operation extremely simple.

    11. The injection port, detector, and converter are all designed with modularity, making disassembly and assembly very convenient. Even those without any experience in operating chromatography instruments can easily disassemble and replace them.

    12. The oversized column box makes it more convenient to disassemble and assemble the chromatographic column.

    13. Equipped with automatic ignition function, the hydrogen flame detector does not require an increase in hydrogen gas. Simply touch the ignition button to automatically ignite, making it more convenient and reliable.
