SI-19KA Certification Ammeter with Shunt

SI-19KA Certification Ammeter with Shunt

DC and True RMS AC Ammeter for Certification of Mag Units and Power Packs

Low Cost Shunt Ammeter for Certification of Mag Units and Power Packs

The SI-19KA-CERT Digital Certification Ammeter is designed to provide a low cost, high accuracy display of output kilo amperes with infinite hold, auto reset and update functions that will meet or exceed all industrial and MIL specs. The high visibility LED digital panel meter displays the output current in kilo amperes. The meter holds this reading indefinitely for accurate recording of the last mag current shot. As each mag shot is taken, the meter will automatically reset, compute and display the new reading in less than .40 seconds.


  • Inexpensive
  • Meter calibration adjustments for zero and gain
  • Holds last reading or can perform continuous readings, for very low current readings below 100 amps
  • LED Display, 3 1/2 digits, 19.99KA
  • Hi Accuracy True RMS AC convertor
  • Hi accuracy DC average circuit assures correct displayed value regardless of which DC wave form is being recorded, 1ph hwdc, fwdc, 3ph fwdc
  • AC power with included cord, no batteries to replace
  • Shunt input jack with hi accuracy (0.1%) shunt
  • Comes with with cert and 5 year warranty
  • Shunt Triggered



Standard Meters are both TRUE Average DC and TRUE RMS AC calibrated for operation from the included 50mv/1000 Amp meter shunt clamped between the heads of your Mag unit or power pack ammeter. Meters are fully calibrated and the shunt is also certified to .1% accuracy, using NIST traceable test equipment from an accredited 17025 calibration lab. There are 3 different sizes of current shunts available, depending on what max mag current you will want to measure. This ammeter can read up to 19,990 amperes.
