AEMC SR661 AC current probe is ideal for industrial and utility environments and was designed for DMMs, recorders, loggers, oscilloscopes, power and harmonic meters. It is built to the highest safety and performance standards including the CE Mark and is UL approved for Canada and United States.

Excellent transformation and low phase shift, plus a broad frequency response, permit accurate measurements of current for power and power quality measurements. The high quality magnetic cores and uniform windings provide sensitivity for very low level current measurements, as well as measurements up to 1200Aac. The SR661 provides an accurate voltage output of 1mV/A to 100mV. This voltage output enables instruments without current ranges to measure, display log currents through an AC voltage range or measure very low AC.
