Electrical Ohmmeters

GAO’s electrical ohmmeters are devices used to measure electrical resistance. Resistance is the opposition that a material offers to the flow of electric current, and is measured in units called ohms. GAO Tek’s ohmmeters work by passing a small current through the circuit or component being tested and measuring the voltage drop across it. By knowing the current being passed and the voltage drop, our electrical ohmmeter can calculate the resistance of the component using Ohm’s law (R=V/I).

GAO’s electrical ohmmeters are composed of power source, measuring instrument (usually a galvanometer), and resistor.

The alternative names of ohmmeters include resistance meters, impedance testers, resistance measuring devices, ohm gauges, electrical resistance meters, impedance meters, ohmic instruments, resistor testers, conductor resistance meters, electrical impedance meters, ohmic testers, conductance meters, resistance measurement tools, electric resistance gauges, impedance analyzers, ohm detectors, conductivity meters, resistance testing equipment, impedance checking devices, and ohm readers.
