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.

GAO Tek’s electrical ohmmeters have the following functions:
- Testing Resistance - GAO's ohmmeters are used to test the resistance of resistors, capacitors, and coils. By measuring the resistance of these components, technicians can determine if they are functioning properly or if they need to be replaced.
- Continuity Testing - Our ohmmeters can also be used to test for continuity in a circuit. Continuity is the ability of an electrical circuit to allow current to flow from one end to the other without interruption. By measuring the resistance of a circuit with an ohmmeter, technicians can determine if the circuit is continuous or if there is a break in the circuit.
- Troubleshooting - GAO Tek’s ohmmeters can be used to troubleshoot electrical circuits and components. By measuring the resistance of various parts of a circuit, technicians can isolate and identify faulty components that may be causing problems.
- Quality Control - Our ohmmeters are also used in quality control processes to ensure that electrical components meet certain specifications and standards.
GAO Tek’s electrical ohmmeters are rugged, versatile and precision measurement instruments. They comply with applicable industry standards such as ANSI/IEEE C57.13.1, NFPA 70E, ASTM D257 and MIL-PRF-55342.
