The GenRad 1491 Decade Inductance Box is the most accurate decade inductor commercially available. The 1491, has a max inductance of 11 H with a resolution of either 1 mH or 100 µH.

The decade switch has high-quality ceramic stator and-rotor members and well-defined ball-and-socket detents. All contacts are made of a silver alloy and have positive wiping action. Shielded toroidal cores are used for small mutual inductance and minimum effect from external fields.

  • Most accurate decade inductor commercially available, accuracy's as good as 0.8%
  • Inductance range from 1 mH or 100 µH to 11 H
  • Shielded toroidal cores for small mutual inductance and minimal effect from external fields
  • Sealed against moisture for long-term stability
