This range of low cost 4 terminal calibration resistors combine high accuracy, class 0.02, long-term stability and permanence of calibration in a compact unit.
Constructed using carefully selected low temperature coefficient Manganin or Zeranin wire, depending upon value, and mounted to ensure mechanical stability, these resistors will provide a cost effective addition to any laboratory or workshop.

Typical applications include:
calibration reference, accurate current measurement, instrument calibration and accurate shunt resistor.

Main areas of application:
- for tests of measuring bridges or electrical temperature measuring equipment
- for laboratory setup of a Wheatstone bridge
- for a defined current characteristic at a defined voltage
- as shunt resistor for current measurement
- as part of standard equipment in research laboratories


A variety of values are available, see table below:
