What is a Clamp Meter?

For the uninitiated, a clamp meter is a type of electrical testing tool that can measure the magnitude of a current through a conductor without touching it or disconnecting the circuit/system.

It uses a jaw-like structure that can be fitted around a conductor (an insulated wire, for instance) to detect the magnetic field generated by the conductor in real time.

It works on the principle of “transformer action” to detect a fraction of the current, and then converts the value into a higher resolution.

This contactless measurement feature is what makes clamp meter an essential tool for electricians working in high energy environments.

Types of Clamp Meters

There are different types of clamp meters available in the market, and users can select them depending upon their requirements.

There are meters that measure both AC and DC, models that also measure quantities like temperature and frequency, and also flexible clamps that can be used to measure current in hard-to-reach areas.

Clamp meters are majorly used in assembly lines, automation and HVAC environments, and areas where disconnecting the system for current measurement is difficult.

Clamp Meter vs Multimeter

Best Clamp Meter Reviews

Compared to general-purpose digital multimeters (DMM), clamp meters have the additional feature of contactless current measurement.

They are mostly similar in their functions with another difference being the resolution. DMMs give readings in higher resolutions whereas clamp meters are restricted to hundredth of a unit.

Having said that, it makes sense for a professional electrician to own both a DMM and a high-quality clamp meter.
