Cropico CR Calibration Resistor
High accuracy, cost effective 4 terminal calibration resistor
Cropico CR Calibration Resistor
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 resistors.
