The Seaward RS3/0.1 resistance standard is constructed using carefully selected low temperature coefficient Manganin or Zeranin wire, depending on the value, mounted on formers which have a high mechanical stability. The wires are wound in a strain free manner and heat treated to remove any stresses. They are also artificially aged under the strictest control. The result is a standard of high quality with long term stability and permanence of calibration combined with a low temperature coefficient.

Seaward offers the widest range of standard values available today.

The RS301 also offers a high current carrying capability which makes them ideal for applications where precise current needs to be measured. This product has a resistance value of 0.1 ohms.
