The OWON CM2100B is the Bluetooth-enabled model in the CM2100 smart AC/DC clamp meter series. It supports compact current and voltage troubleshooting, resistance and capacitance checks, frequency and duty-cycle measurement, NCV, VFC filtering, and app-connected recording workflows.
Key features
- Smart AC/DC clamp meter for current, voltage, resistance, capacitance, frequency, duty cycle, diode, and continuity
- 100 A AC/DC current range and 600 V AC/DC voltage range
- 20000-count true RMS automatic range display
- CM2100B Bluetooth module for recording/app-connected measurement workflows
- NCV and VFC modes with 17 mm jaw capacity in a compact body
