• Development of a light-weight low cost self potential unit

      Zonge, K.L. (University of Alaska Mineral Industry Research Laboratory, 1968)
      A lightweight, low cost self-potential unit has been developed using solid state components. The parts for the basic unit including batteries, copper sulfate pots, and hookup wire costs approximately $70.00. The device is instant reading and weighs two pounds. The batteries used have a shelf life of ten years and an estimated operation life (based on continuous use for ten hours per day) of sixty days. This instrument was developed specifically for the Alaskan prospector who is concerned with weight and cost of field instrumentation.
