Chauvin Arnoux MiniFlex MA200-250 [P01120571] 300A AC Current Probe w/25 cm Sensor Length. The MiniFlex® MA200 is a flexible sensor comprising an active part (Rogowski coil) linked to a casing containing electronics. Unlike a current clamp with magnetic circuits, the MiniFlex® models are flexible and are not subject to magnetic saturation constraints, so they offer excellent linearity, low phase shift and a large dynamic range for measurement (up to several kA) while remaining easy to use. The oscilloscope probes in the MA200 series a specially designed for viewing alternating currents in order to assess the transition and propagation times on electrotechnical equipment. The sensors’ flexibility makes it simple to clamp and measure any conductor, whatever its type (cable, busbar, strand, etc. and accessibility. The click-lock system for opening and closing the coil is specially designed for use with safety gloves. The casing can be connected to any oscilloscope equipped with an AC voltage input.
