PPM low resistance meters feature 4 wire kelvin measurement technique. This technique compensates for the resistance in the test leads. PPM low resistance meters accurately measure micro ohm, milli ohm to sub percent accuracies. These meters are also known as Micro ohmmeters, bond meters, milli ohmmeters, ducters. Some are intrinsically safe for use in jet aircraft fuel applications.
