RS3 The RS3 range of resistance standards are 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. We offer the widest range of standard values available today. In addition we are able to manufacture for special applications (e.g. Pt100 simulation) special values to customer requirements. The RS3 range also offers a high current carrying capability which makes them ideal for applications where precise current needs to be measured. 4 TERMINAL CONSTRUCTION, HIGH STABILITY RESISTANCE STANDARD WITH WIDE RANGE Resistance Decades & Standards key feature RS3 Wide range 0.0001 ohm to 1 Mega ohm n Excellent load coefficient n Special values made to order n 4 terminal construction n Can be used in air or oil bath n Each standard supplied complete with calibration certificate n Bracken Hill, South West Industrial Estate, Peterlee, County Durham, SR8 2SW United Kingdom Tel: +44 (0) 191 586 3511 Fax: +44 (0) 191 586 0227 Email: sales@cropico.com Web: www.cropico.com
