Soil resistivity testing equipment is required to measure how well the ground resists or conducts the flow of electrical current. Accurate calculations are important when dealing with systems that require sending current underground. It's critical to have precise and reliable tools when conducting a soil resistivity test. Certified Material Testing Products knows this and has the soil resistivity testing equipment you can trust.
