The Resistivity Meter is a portable measuring instrument designed to give a quick, reliable measurement of the resistivity from a small sample, expressed in Ohm-Meters. This transistorized meter accurately measures the resistivity of fluids, slurries, and semi-solids with resistivities from 0.01 to 10 Ohm-Meter 2 /Meter. This Ohm-Meter reading can also be converted into parts per million Sodium Chloride using the Nomograph supplied, making it easy to measure resistivity.
