LR-9860 Transformer Oil Chromatograph Tester is a multifunctional specially used in insulating oil dissolved gas content analysis of gas chromatograph, the instrument adopts the advanced double column in parallel, series thermal conductivity detector, methane conversion furnace, double hydrogen flame detector gas path flow, adopting three signal output technique at the same time, once completed sample dissolved in insulating oil of H2, O2, N2, CO, CO2, CH4, C2H4, C2H6, C2H2 nine kinds of gas composition analysis of the whole, with a powerful, excellent performance, good separation effect, high sensitivity, good reproducibility, simple operation, low fault rate and aesthetically pleasing, etc, can completely meet the needs of the insulating oil multitasking test analysis, the performance indicators are better than national standards, is the user’s preferred insulating oil analysis.


Performance characteristics

  1. Englishdisplay, Englishkeyboard 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.
  2. Automatic monitoring of each heating area will automatically cut off the heating power.
  3. It has the function of breaking air. When the load pressure is lower than 0.1mpa, the instrument will automatically alarm and cut off the heating power and the thermal conduction bridge current.
  4. with parameter storage function, the instrument is turned off after the next boot need to open the instrument power master switch, the instrument will automatically according to the state before the last shutdown operation, realize the function of the real “box” boot, or power to restore power after the instrument will automatically return to power in front of the running state.
  5. With the function of fault diagnosis, the instrument can detect the running parameters in real time, and the microcomputer system will automatically protect the instrument when abnormal system occurs.
  6. the process design of pneumatic system adopts unique voltage, reduce the gas injection pressure fluctuations on the impact of the detector, thus maximum limit reduces the impact peak to analysis the influence of ensures the high reproducibility and high accuracy of the results of the analysis.
  7. the whole machine classic three box type design, adopted the advanced isolation circuit and chi road three box type design, easy to control and maintenance, make the instrument more neat and beautiful appearance, more to improve the safety of the instrument operation.
  8. The gas, hydrogen and air are indicated by the pressure gauge, so that the operator can be clear and easy to operate on the chromatographic analysis conditions.
  9. The main and key components are imported components, which extend the service life of the whole machine and reduce maintenance costs.
  10. The instrument is fully debugged before leaving the factory. After the instrument arrives at the site, the user can only turn on the power supply after ventilation, and the operation is extremely simple.
  11. The sampling port, detector and converter are all modular design. It is very convenient to remove and install, and the operator can easily disassemble and replace without any color spectrometer operator.
  12. Super-large cylindrical box (300 x 285 x 260mm), which makes it more convenient to remove the column of chromatographic column.
