Precision Double Bridge 2752 (Lab-Grade Accuracy)

  • Laboratory-grade accuracy ±0.03 to ±0.05%
  • Quick readout without error
  • Excellent long-term stability: The resistance elements are made of selected manganin wire, stabilized by both artificial and natural aging after being wound.
  • Perfect guard system
  • Stable measurement: The dial switches offer low contact resistance and little change due to aging, giving stable operation. Inner/outer contact type plugs are used for changing the multiplication factor, assuring little change in the resistance due to reinsertion of plugs.
  • Built-in standard resistors
  • Bar resistor measurement
