Chauvin Arnoux D31N [P01120050A] 500A/1000A/1500A AC AC Current Probe Adapter. Chauvin Arnoux D31N [P01120050A] 1 - 1800 A AC Current Probe Adapter. The Chauvin Arnoux D31N AC 1600/1200/1800A (1A AC)[F] Current Probe is a ultra-portable current probe that can be used with a wide range of testing equipment. This D Series Chauvin Arnoux current probe allows for exact measurements of even the heaviest currents, up to a level of 3000AAC. The Chauvin Arnoux device can help you get exact change, low-phase displacement and high-bandwidth measurements, with simple operation that means that you will quickly get to grips on how to get the best results. Simply squeeze the handles and the clamp will open, allowing you to use the current probe on large wires and pieces of equipment. The non-contact nature of the Chauvin Arnoux D31N AC 1600/1200/1800A (1A AC)[F] Current Probe also means you do not have to turn off the current to take measurements of equipment, either.  The current probe has rectangular-formed clamps so that you can measure large cables or conductor rails. Furthermore, its True RMS measurement for precise exact signal reproduction is a great feature, and the current probe is designed for use with oscilloscopes or other devices that use a BNC interface.
