Clamp Meter

A clamp meter, also known as a current clamp or amp clamp, is an electrical testing tool that is used to measure the amount of electrical current flowing through a conductor without the need to physically disconnect it. It works by clamping around the conductor, creating a magnetic field that induces a voltage that can be measured by the device.

Clamp meters are commonly used in a variety of industries, including electrical, HVAC, and automotive, for measuring both AC and DC currents. They are useful for measuring currents in hard-to-reach locations, as well as for measuring currents in live circuits without the need to interrupt the circuit or make contact with the conductor.

Some clamp meters also have additional functions, such as the ability to measure voltage, resistance, and frequency. They typically have a digital display for easy reading of the measurements and can be handheld or mounted on a stand.

Overall, a clamp meter is a versatile and essential tool for any electrician or technician who needs to measure electrical current accurately and safely.
