Terrameter                                                                                     Products

Soil resistivity is one of the most important factors in selecting a ground-bed location and it is measured in ohm-cms. Terrameter or Resistivity meters is used to measure soil resistivity and it works on simple principal of feeding current through a pair of electrode and measuring potential developed across another pair of electrode. Emtech Control Terrameter does this measurement automatic with all calculations and protections.
