Precision AC Current Shunt


Measure Tech's AC current shunt (model# EL-9800) has expanded AC current measurements far beyond existing levels. For the first time, the new primary standard allows current calibration to be certified by the National Institute of Science and Technology (NIST) to 100 amp and 100 kHz. This product has been tested by NIST and approved by the U.S. Air Force to be used in all of the Air Forces precision measurement laboratories.


  • Excellent ac accuracy up to 100KHZ
  • Handles up to 100 amps and 100 kHz
  • Output stability
