The Cropico RS3 range are a highly accurate and reliable resistance standard.

The most desirable feature in which any resistance standard should excel is permanence of calibration, this has been achieved by the experience gained over many decades in the manufacture of precision resistors, with the careful selection of resistance material, a rugged strain-free construction and a carefully controlled heat treatment and ageing process.

In order to obtain the optimum performance from the standard, we recommend regular annual certification. A resistance standard which has been carefully used within the limits of the manufacturer's specification increases in usefulness with time, as its complete history is recorded, enabling the user to determine its value at any time.

The RS3 range of resistance standards are constructed using carefully selected low temperature coefficient Manganin or Zeranin wire, depending on 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 also are 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.

Due to the requirement for artificial ageing, delivery time for these models can be up to 6 weeks. Please contact us for a confirmed delivery date. A calibration certificate is supplied with this unit.
