Clamp-on current probes or "current clamps" enable the user to measure currents without breaking the electric 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.
The Pico range of current clamps can be used with Pico oscilloscopes and data loggers, as well all major brands of oscilloscope and multimeters.
