DC Resistance Tester · Micro‑ohm meter
GPS‑8815C / 8815E
Compact benchtop micro‑ohm meters with 4‑wire (Kelvin) measurement,
fast sorting and temperature compensation for lab and production.
8815C: 1 µΩ–20 MΩ · 0.05%
8815E: 1 µΩ–30 kΩ · 0.1%
Up to 140 rdg/s (C)
RS‑232 (C: + Handler)
Key features
4‑wire (Kelvin)
Low‑ohms accuracy with shielded 4‑terminal measurement.
High throughput
Up to 140 readings/s (8815C) with BIN sorting & beeper.
Automation‑ready
SCPI via RS‑232; 8815C adds Handler (PLC) & external trigger.
Temperature comp.
Compensate 0–80 °C (±0.2 °C) for stable results.

Which model should I choose?
- 8815C: widest range (to 20 MΩ), fastest throughput, 14‑bin sorting, handler I/O.
- 8815E: cost‑effective choice for low‑resistance work up to 30 kΩ with RS‑232.
Where does it excel
Low-ohms components & interconnects
- Busbars, shunts, bonding straps
- Relay/switch/contact resistance (mΩ–Ω)
- PCB traces, vias, ground planes
- Battery tabs, welds & crimps (quality checks)
Coils, windings & magnetics
- Armatures, stators, transformer windings
- DCR verification and copper loss estimation
- Lead/termination integrity and balance checks
Production sorting & automation
- 8815C: up to 140 rdg/s with 14-bin comparator
- Handler (PLC) I/O & external trigger (8815C)
- SCPI via RS-232 for line integration (both models)
Temperature-aware measurements
- 0–80 °C temperature compensation (±0.2 °C)
- Normalize DCR to reference temp for better repeatability
- Useful for copper conductors, coils and busbars
Choosing between models: 8815C for highest throughput, widest range and handler I/O; 8815E for cost-effective low-resistance work with RS-232 control.
