High-resistance meters are measuring devices that have been developed to precisely determine high electrical resistances. They are primarily used for testing insulation resistance, for example in quality assurance of insulating materials, in cable and wire testing and in various areas of the electrical industry. They are used to test the electrical safety and reliability of components and systems.
Depending on the version, high-resistance meters differ in terms of measuring range, electrode type, operating mode and additional functions such as data logging or interfaces. The devices are available as individual measuring instruments or as complete measuring kits with accessories.
