    Ohmmeters

    An ohmmeter is a meter used in the measurement of electrical resistance and continuity of an electrical circuit and components and is available in a range of sizes, voltages and types, each with varying levels of accuracy. Ohmmeters (or ohm meters) are available in three main variations including micro-ohmmeter (for measuring low resistance), standard ohmmeters for general purpose and meg-ohmmeter (for measuring high resistance), all of which measure electrical resistance in ohms. There are various types of meters available with different sensitivity levels which include micro, mega and milliohm meters.

    Typical Applications for Ohmmeters

    Ohmmeters are used in a wide range of applications where the measurement of electrical resistance is required. Ohmmeters are commonly used in the following areas:

    • Laboratory and Research Environments
    • Production
    • Household Troubleshooting

    How does an Ohmmeter work?

    Ohmmeters work by passing a small current through a sample, allowing the instrument to measure the voltage drop and how much an object resists allowing the current to flow through, highlighting the resistance in ohms. It's important when using an Ohmmeter to sustain accurate measurements, this is done through calibration to UKAS standard or RS offers an in-house calibration service to RSCAL service.
