CP024 AC/DC Current Probe

CP024 AC/DC Current Probe

The OWON CP024 is a high-precision AC/DC current probe designed for engineers, technicians, and laboratory professionals who require accurate current measurements without breaking the circuit. Supporting a wide current range from 4A to 400A, it is ideal for power electronics, automotive diagnostics, inverter systems, and maintenance applications. Featuring automatic zeroing, wide bandwidth response, and low remanence, the CP024 ensures high accuracy and reliability when measuring steady-state or transient currents. With its compact clamp design and safety-rated jaw opening, it enables safe, convenient, and real-time current monitoring using any oscilloscope or data acquisition device with a standard BNC interface.
