Owon AC/DC Clamp Current Probe
The OWON CP-07+ is a compact and high-precision AC/DC clamp current probe designed for accurate current measurement in low-power circuit testing, signal analysis, educational labs, and general electronic diagnostics. With a measurement capability ranging from 400mA to 4A and a resolution of 0.1mA, it delivers excellent sensitivity for both micro-current and moderate current applications. Featuring auto zeroing at power-on, wide bandwidth up to DC 1MHz, and a reliable clamp design, the CP-07+ is ideal for capturing dynamic current signals in switching power supplies, small motors, audio circuits, and embedded systems. Its durable build, ergonomic form factor, and compatibility with oscilloscopes make it a trusted tool for engineers, researchers, and technicians.
