A tool for measuring AC current in confined spaces or challenging-to-reach places is the Kyoritsu KEW 8133-03 Flexible Clamp Sensor. It is a flexible and practical tool for electricians, technicians, and engineers because it is made to be used with compatible clamp meters, oscilloscopes, and multimeters.
The KEW 8133-03 is ideally suited for usage in limited locations because of its flexible sensor head, which can be twisted and molded to fit around cables or conductors. The sensor has a frequency range of 40Hz to 10kHz and a measuring range of up to 3000A AC.
