GAOTek supplies professional-grade portable ohmmeters that accurately measure the electrical resistance between two points on a circuit. Our ohmmeters are battery powered. This is needed when the two probes (red: the positive side of the circuit, black: the negative side of the circuit) are connected to the two points in the circuit, where the desired measurement is needed to take place. The ohmmeters send their currency through the circuit when the circuit is turned off. Units of Ohms, symbolized by the Greek letter Ω (omega), is the predominant way to measure electrical resistance. Following Ohm’s law, when the current is passing through a circuit is at its maximum, the resistance is said to be the smallest. These products are available in the United States, Canada and internationally.

If you have any questions about the GAOTek Ohmmeters or would like a price quote on any of our testers, please feel free to contact one of our product experts who would be more than happy to assist you.  Click here to contact an expert.
