R1L-C Portable Ground Resistance & Bond Meter

Brand: Tegam

The Model R1L-C is a Ground Resistance Ohmmeter designed to measure grounding system resistance, as well as soil resistivity, over ranges from milliohms to 20 kiloOhms full scale. 

The R1L-C is capable of Wenner, Fall of Potential, 62% methods as well as bond and continuity measurements. 

Two, three and four are standard for this instrument.
