High-precision Dual-plunger Infusion System with Strong Test Data Parallelism
Flow precision 0.8%, accuracy＜±1%, stable output under 6000psi high pressure with extremely low pump pulsation; equipped with automatic solvent compressibility factor compensation function to offset solvent volume loss under high pressure.

Application Value: Stable long-term test data for single unit, furfural test reports can be directly applied to power equipment condition assessment. For mass deployment of multiple units, deviation of test results on the same sample among different instruments is tiny, easily passing CMA/CNAS laboratory comparison evaluation and reducing sample recheck workload.
 

Flow Path Special Optimized for Power Insulating Oil Test, Compatible with Industry-specific Mobile Phase
Separated stainless steel high-pressure pipeline and special PEEK low-pressure pipeline with automatic plunger flushing flow path. Clear compatibility list of furfural eluent avoids pipeline corrosion, embrittlement and leakage.

Application Value: The wear rate of pipelines and sealing parts reduces by 30% during long-term mass test of transformer oil samples. No frequent replacement of pipeline fittings, cutting maintenance labor and consumable budget, suitable for daily continuous test working mode of laboratories.
 

Large-capacity Program Storage + Multi-device Linkage Control for Standardized Mass Management
Single unit stores 60 gradient test methods with 20 time segments for each method; bidirectional RS232 communication port supports multi-pump linkage and synchronous program copy.

Application Value: Multiple standard insulating oil test methods can be stored in single unit and recalled by one click without repeated setting. For mass procurement of multiple units, industry standard furfural test programs can be imported uniformly with centralized lab control, lowering man-hour of staff training and equipment debugging.
