Seaward Cropico RS3/1 [930024] High Stability Resistance Standard, 1 Ohm

The Seaward RS3/1 Cropico RS3 High Stability Resistance Standard, 1 Ohm is constructed using carefully selected low temperature coefficient wire, 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. The RS31 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 1 Ohm.
