Model 2781 is an one-ohm prime resistance standard ideally suited for preservation and maintenance of resistance values in laboratories and instrument rooms. In order to ensure long-term stability as a reference standard,  resistors are manufactured under close supervision with special consideration given to the use of carefully selected Manganin wire  for resistor elements. Each element is bifilar wound, carefully adjusted, and thoroughly annealed.
