30 A AC/DC precision current probe, BNC connector

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.
