Clamp Meters

Clamp meters help electricians, technicians, and maintenance professionals measure current on conductors during electrical testing, troubleshooting, and routine maintenance. Options in this category support AC or AC/DC current checks, with selected models also offering voltage, resistance, frequency, continuity, diode, capacitance, duty cycle, or ground-resistance testing functions.

Helpful Buying Guide

Choose a Clamp Meter for the Measurements You Need

Start with the current type and range required for the work, then compare clamp size, measurement functions, display features, and documentation or data-handling needs. The available selection includes compact meters for routine current checks, higher-capacity AC models, ground-resistance testing equipment, and related accessories.

Use Cases

Support routine electrical testing

Clamp meters are used to check current on conductors during troubleshooting and maintenance. Depending on the model, they can also support voltage, resistance, continuity, frequency, diode, capacitance, and duty-cycle checks.

How to Choose

Match range, current type, and access

Choose AC-only or AC/DC measurement based on the work. Compare capacities from 30 A to 600 A, and consider compact or 0.5-inch jaw options for tight spaces versus a 1.2-inch circular jaw for large cables up to 500MCM.

Applications

Compare specialized testing needs

For low-current work, select a 30 A mini model with 0.1 mA resolution. For grounding evaluations, a clamp-on tester measures ground resistance and true RMS AC leakage current without auxiliary ground spikes.

Additional Information

Consider records and useful features

Data hold supports viewing and recording readings. Other available features include 150-reading memory, 116-point data logging, programmable Hi/Lo alarms, non-contact voltage detection, integrated flashlight, auto power-off, and documented certification on select models.
