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. FEATURES 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   APPLICATIONS For precision measurement applications. The calibration of laboratory or workplace equipment.
