Since 1991 we have been supplying the world with test and measurement equipment. At Pico we realize that your choice of test accessories can be almost as important as your choice of test equipment. Here you can purchase a variety of test and measurement accessories quickly and securely online.
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 shut 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 PicoScope Oscilloscopes and PicoLog Data Loggers, as well all major brands of oscilloscopes and multimeters.
The TA138 is a current clamp for AC-only current measurements. Its single range is capable of measurements from 0.1 A to 200 A. Ideally suited for use with the PicoLog CM3. Fitted with 4 mm (banana) plug type connectors.
