Sales Volume and Application Scenarios of Goldhome Hipot Handheld Contact Resistance Tester
Handheld Contact Resistance Tester (HM6090S-100A) Core function: Micro-ohm-level contact resistance/loop resistance measurement for various equipment Suitable for power and industrial applications
Application Scenarios:
1.Power Switchgear Testing: Compatible with high/low-voltage switches, SF6 circuit breakers, vacuum circuit breakers, and main contacts of disconnect switches. Measurement range: 0.1μΩ–2mΩ. Resolution: 0.01μΩ. Accuracy: ±(0.5% + 2 digits). Capable of outputting DC 100A test current (current ≥100A when testing at 2mΩ). Test duration selectable at 1s, 10s, 30s, 60s. Fully compliant with DL/T845.4-2004 standard. Suitable for field maintenance and factory acceptance testing.
2.Small Conductive Component Testing: Suitable for wires, switch contacts, relay contacts, busbar joints, cable joints, and welded points. Test current supports multi-range adjustment (30A, 50A, 80A, 100A) corresponding to different ranges (30A range achieves 0-50mΩ), enabling precise capture of minute contact resistance deviations.
3.Power Equipment Testing: Suitable for transformer bushing conductors, small motor leads, and reactor connection points. Weighing only 1kg with dimensions of 200mm × 100mm × 60mm, this handheld portable device meets both laboratory fixed testing and on-site mobile testing requirements.
4.Specialized Testing for Specific Industries: Covers factory acceptance testing at high-voltage switchgear manufacturers and transformer plants, as well as contact resistance verification in rail transit and renewable energy sectors (e.g., wind farm substations). A single charge enables ≥100 switch measurements (1-second test duration), suitable for outdoor power-free scenarios.
