Micro Ohm Meter
The Motwane LR-2045 is crafted to deliver incredibly precise measurements of very low resistances, making it a trustworthy option for electrical testing, maintenance, and diagnostics.
It can measure resistance values as low as 0.1 μΩ with remarkable precision.
It spans a wide range from 2 mΩ to 2 kΩ, offering a fine resolution of 0.1 μΩ.
- 4½ digit LED display.
- Resolution 0.1µΩ on 2mΩ range.
- RS 232 PC Interface.
- True 4 wire resistance measuring technique eliminates lead resistance errors inherent in 2 wire Measurements systems.
- Pulse Mode Operation.
