Decade Resistance Box - PL 33

Description

Decade Resistance Box consists of decade switches with resistors. Each decade switch has 1-10 positions in addition to zero position. Specially designed switch with self cleaning and silver plated contacts ensure very low contact resistance and long life.

Resistances of 10 k ohms & lower are made of non-inductively wound selected manganin. Coils are heat treated and aged for long term stability.

100k and 1M ohm decades have selected & precision metal film resistors of very low temperature co-efficient. All the decades are housed in metallic/wooden rugged casing and are provided with knobs having ribs for comfortable operation. Decade Resistance Boxes are available with 4, 6, 7 & 8 decades and offer a wide choice of resistances to meet with almost every requirement in industry & laboratories.

  • Manganin Resistance Coils
  • Non-inductively wound & aged resistors
  • Low temperature co-efficient
  • Sturdy, rugged & trouble free service
  • 4, 6, 7 & 8 decade models
  • Wide choice of models from 0.01 ohm to Megaohm
  • Very low contact resistance switches
