Clamp-on probes connect to compatible multimeters or other testing equipment to sense and measure electrical currents. They have solid jaws that clamp around conductors without disconnecting and interrupting the power supply. With an extendable cord, they are often used to connect with conductors in hard-to-reach locations.

These lightweight current probes have flexible jaws that wrap or loop around conductors. They connect to compatible multimeters or other testing equipment and are often used on conductors of different shapes and sizes, thick bundles of cables and wires, or circuit breaker panels and bus bars in hard-to-reach areas.
