GROUND RESISTANCE TESTER Ф4103-М1

The device performance is splash and waterproof.

 

device-f4103

 

Ground resistance tester Ф4103-М1 is designed for measuring the resistance of grounding devices of any geometric dimensions, soil resistivity and active resistance in the presence and (or) in case of no interference.

 

 

 

 

Specifications:

 

Measuring ranges and permissible values of potential resistance and current electrodes are given below:
