Hantek CC-65 AC/DC Multimeter Clamp Meter
This clamp meter combines current measurement capabilities with compatibility for both digital multimeters and oscilloscopes. It targets power circuit analysis and malfunction diagnosis, making it suitable for motor drives and frequency converter testing. The BNC interface facilitates easy waveform observation, while the device covers a broad DC/AC range for general electronics work.
Hantek CC-65 AC/DC Current Clamp Transducer
This transducer extends the CC-65’s reach to digital multimeters and oscilloscopes with a precise BNC connection. It suits applications requiring synchronized current data alongside voltage measurements, such as motor control and power electronics timing analysis. The extended bandwidth supports quick waveform capture while maintaining measurement fidelity.
Hantek CC-650 AC/DC Current Clamp
The CC-650 offers a higher current range and broader DC measurement capabilities, making it well suited for power circuits and malfunction analysis within consumer electronics, motor drivers, or industrial controls. With a wider dynamic range, it captures large current spikes without saturating, while still enabling accurate low-current readings.
OWON CP024 Current Probe for Oscilloscope
OWON CP024 is designed to extend oscilloscope capabilities with a wide 200 kHz bandwidth and a flexible range that covers automotive and power electronics testing. Its amorphous alloy core reduces core losses, delivering low-noise current readings across several ranges (1 mA to 400 A), which is ideal for waveform analysis and precise current profiling in complex circuits.
HANMATEK CO601 3-in-1 Clamp Meter & Oscilloscope
CO601 combines oscilloscope functionality with clamp meter, enabling measurements of current, voltage, frequency, duty cycle, resistance, and capacitance. It includes non-contact voltage detection and data logging via BLE, which is useful for on-site diagnostics, field service, and educational labs. Its 1 MHz bandwidth supports rapid waveform capture for transient analysis.
Buying Guide: Key Purchase Considerations
Bandwidth and frequency response are critical when selecting a current clamp for oscilloscope use. Higher bandwidth captures faster transients and reduces measurement distortion, which matters for motor drives and switching power supplies. Consider clamps with at least 20 kHz bandwidth for general electronics and up to 200 kHz or more for automotive or high-speed switching tests.
Current range and accuracy determine how well the clamp handles both small and large currents. Look for devices with 20 mA to 65 A or wider, and assess how the scale is calibrated. A safe practice is to start with the mid-range and climb as needed to avoid saturation and maintain accuracy.
Connector compatibility is essential. BNC is the standard for oscilloscope probes, so ensure the clamp provides a reliable BNC output or a direct oscilloscope interface. If the clamp is primarily for DMM use, verify how easily it integrates with an oscilloscope.
Ease of use and data features add practical value. Non-contact voltage detection, data logging, and Bluetooth or smartphone syncing are helpful for field diagnostics and documentation. If you work in a lab, an integrated oscilloscope mode can streamline your workflow.
Durability and safety ratings matter in power electronics testing. Check insulation, CAT ratings if available, and build quality, especially for high-current measurements near equipment under test. A comfortable grip and compact form factor improve usability in tight lab spaces.
Price and support are practical considerations. Compare warranties, accessory availability (test leads, BNC adapters), and vendor support. For oscilloscopes, verify compatibility notes and any required adapters to avoid misinterpretation of current waveforms.
In sum, select a clamp with sufficient bandwidth for the target tests, a current range that covers your typical measurements, robust BNC connectivity, and useful data features. The five products reviewed here provide a balanced mix of performance, versatility, and practical use cases for oscilloscope-based current analysis.
