Clamp Meters

Clamp meters are essential tools for every professional that have to deal with electrical circuits. These instruments offer valid measurements of alternating or direct current flowing through a conductor. Clamp meters approximate the measure to the nearest tenth or hundredth safely and quickly. Quite often, they are used with other measurement instruments such as DDMs. Clamp meters are irreplaceable when a circuit cannot be cut off to take the measure. Besides amperage, clamp meters can provide data about voltage and resistance. While some models can switch to measure AC or DC, other models work with only one of these current types.

A typical clamp meter consists of two ferrite iron jaws that are set around the wire; a handle with a display allows for reading the information about the magnetic field generated by current flowing through the conductor. AC clamp meters apply the principle of the current transformer to take the measurements, while DC types exploit the hall effect. Operating within a specific current range, these tools can be damaged or provide wrong data if used improperly. In our online store, we have a large choice of premium clamp meters designed by reputable companies to ensure reliability, efficiency, and safety.
