Pearson Electronics is the original and leading manufacturer for precision current-monitoring transformers used for accurate AC current measurements. The company was founded in 1955 by Dr. Paul Pearson, inventor and patent holder, of the precision wide-band current transformer. The Pearson design plus careful workmanship and quality control produce current monitors with excellent frequency response and amplitude accuracy.
Originally developed for measuring pulse-currents, Pearson Current Monitors™ are now also widely used to measure more complicated transients and periodic signals from a few Hertz to well into the megaHertz region. Please note for non-Canadian purchases, please contact Pearson Electronics directly.
