Soil Pins are constructed of heavy-duty solid stainless steel with a T-Handle. The Soil Pins are used as an electrode in soil resistivity testing with the Wenner 4-pin method. The T-handle and pointed tip makes penetration of dense soils easy. It can be used with the Analog or Digital Soil Resistance Meters.
