The Tinker & Rasor SR-2 Soil Resistivity Meter is a highly accurate and easy-to-use soil resistivity instrument for use with the 2-pin and 4-pin (Wenner) methods of soil resistance measurement. A pin selector switch allows choosing between 2-pin and 4-pin tests without removing cables.
Model SR-2 provides easy resistance readings with a digital 4-1/2 digit display, push-button operation, and an easily adjusted Ohm to MOhm range selector. The display will show in the correct range. Multiply reading with pin spacing multiplier for Ohm-cm.
Use the SR-2 to find soil resistivity for a variety of cathodic protections applications, including pipelines, tanks, wells, etc. Also use for geological and archeological studies.
