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 TA189 30 A high-precision current probe is for applications requiring current measurement without the need to disconnect wiring, using closed-loop Hall effect technology to measure both AC and DC current with high stability over long periods of time. It is ideal for current leakage monitoring and battery discharge testing. When used in conjunction with an active differential voltage probe such as TA041 it can also be used for power quality analysis.
