Model 291 Resistivity Meter The Model 291 Resistivity Meter fills the void between lower performance, lower cost and the
more expensive higher performance instruments. This pocket-sized meter has parallel metal contact rails and jacks for connections to external electrodes or ground. Using a single 9-volt
battery, the unit automatically generates a test voltage of either 10v or 100v. You simply place the instrument on a flat surface of material to be tested, press the button and read the
results from the multicolored LED display. It comes with carrying case, ground lead and calibration certificate.
