How Do You Use An Ohmmeter Or Multimeter To Test Water Conductivity Or Purity?
Pure water (distilled or deionized) lacks the ions to carry current and will test as very high resistance, 10 MegOhm or above. Most natural, spring or tap water used for drinking or processes have or need those ionic impurities. However, measuring water conductivity is a solid way to measure if an item being rinsed in pure water has been cleaned. Measure the distance from the desired testing location to where the DMM can be located. Using the diagonal cutters, cut two pieces of insulated wire, each for the measured distance. Using the diagonal cutters, carefully cut into the insulation about a half inch from the end of one of the wires and twist the wire or cutters to make a circular cut through the insulation without cutting the metal conductor. Use the cutters to pull the cut insulation from the wire. Repeat on the three remaining ends of your two cut lengths of wire. Carefully using the heated soldering iron and solder, press a bared wire end to an electrode and melt solder onto the
