200 A micro‑ohmmeter for accurate loop/contact resistance diagnostics

The GDHL‑200A is a professional loop resistance tester capable of injecting up to 200 A DC current with high resolution (0.01 µΩ), designed for precise measurements in transformers, circuit breakers, busbars, and cable joints.
SKU: 00036
Vendor: Gold mechanical and electrical equipment

The GDHL‑200A Loop Resistance Tester uses advanced high-frequency DC sourcing and digital circuitry to perform reliable loop resistance measurements at selectable currents of 50 A, 100 A, 150 A, and 200 A. It excels in stability and accuracy, maintaining results within ±0.5%±1 digit, with a micro-precision display of up to 0.01 µΩ resolution  . The tester is ideal for measuring contacts in circuit breakers, transformers, switchgear, and welded joints, helping technicians diagnose issues such as corrosion or looseness. Features include digital display, data logging, automatic range selection, USB data export, overload protection, temperature compensation, and portability (~5 kg)  .

Key Features:

  • Output currents: 50 A, 100 A, 150 A, 200 A DC

  • Measurement range up to ~30 mΩ with 0.01 µΩ resolution

  • Accuracy: ± (0.5% + 0.1 µΩ)

  • Digital display, USB data logging, auto-range

  • Safety: overload, overheat, auto-discharge

  • Portable (~5 kg), rugged field-ready design

  • Ideal for maintenance and factory QC

  • CE and ISO certified
