GAOTek provides state of the art, professional grade Ohmmeters for sale to the United States, Canada and Globally. GAOTek Ohmmeters are portable instruments that accurately measure electrical resistance between two points on a circuit. The Ohmmeters have their own power supply through their own battery, and are needed when the two probes (red: positive side of circuit, black: negative side of circuit) are connected to the two points in the circuit where the desired measurement is to take place. The circuit is turned off, which is when the ohmmeter sends its own current through the circuit. Units of Ohms, symbolized by the Greek letter Ω (Omega), are used as a unit of measure when measuring electrical resistance. In accordance with Ohm’s law, when the current is passing through a circuit is at its maximum, the resistance is said to be the smallest.
