Siglent CP4020 current probe
Details
The Siglent CP4020 is an affordable AC/DC active current clamp probe with a DC to 200kHz bandwidth. This probe can safely measure a maximum continuous current of 20Arms and a maximum peak current of 60A. The CP4020 features a BNC connector, which allows for a wide compatibility with most oscilloscopes. With the addition of a BNC to banana adapter, the probe can also be used with other measuring instruments, such as a multimeter. Lastly, the CP4020 can be powered by a 9V battery or the included DC power supply, making it ideal for indoor or field applications.
