Baker Instrument RT45 Low Resistance Ohmmeter, 115VAC

Manufactured by: Baker Instrument / SKF
The RT45 is a kelvin ohm meter capable of accurately measuring low resistances with 4.5 digit resolution. It is intended for production, repair or compliance testing of motors, coils, transformers, cables, thermal devices, resistors and other electrical devices.

Select for Quotation
  • Brand name :  Baker Instrument
  • Item Name :  Ohmmeter
  • UNSPSC :  41113631

Because of its low resistance accuracy, it can be used in a large motor repair shop. In the 200 megohm range, the RT45 has 10 microhm resolution. Because of its high speed, it is suitable for high volume coil production line testing. It can measure resistances up to 200 kilohm.
