Current probes (clamps)
Clamp-on current probes or “current clamps” enable you to measure currents without breaking the electrical circuit. Current clamps are designed with jaws that can be opened, placed around the conductor and clamped closed to form a magnetic loop around the conductor.
Current clamps offer a safe, cost-effective, simple and accurate way to take current measurements.
Our range of current clamps can be used with Pico Oscilloscopes and Pico Data Loggers, as well all major brands of oscilloscopes and multimeters.
