The Big Fink cathodic protection test station is a versatile, high impact resistant, non-conductive above ground terminal for conveniently monitoring electrical currents and potentials associated with all type of underground piping cables and other metallic structures. The big fink is used as a terminal for test leads to read:

- Underground structure to soil potentials.
- Cathodic protection anode currents.
- The resistive integrity of insulation flanges and joints.
- The integrity of insulation between all types of underground metallic structures, such as between a     carrier and its casing.
- Stray currents on all types of underground structures.
FEATURES
