Precision Current Shunt

1μA ~ 250A

Lab Current Standard 1uA-250A Current Range AC & DC Current Shunt AC & DC Current Meter


  • 0.01% High Accuracy
  • 4 1/2 Digit AC & DC Current Meter
  • Built-in Over Current Protection
  • Less than 10ppm / ∘C
  • High Stability & Reliability


  • Model 7550A has five precision selectable Ultra stable Current Shunts which ranges from 0.001 to 10Ω. The Shunt T/C is less than 10ppm, and the internal current meter will measure from 1μA to 250Amps.
  • The Five selector switches, Shunts and the internal 4 1/2 Digit AC & DC Current Meter displays the respective shunt current. Adding an external DVM (with 5 1/2 digit or higher) will increase both resolution and current reading accuracy.
