Ohmmeters

An ohmmeter is a type of meter used in the measurement of electrical resistance and continuity of an electrical circuit and components and are 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.

Application

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 generally 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.
