SRR Series High Accuracy Standard Resistor

  • Product No:SRR Series
  • Manufacturer:IET LABS, Inc. 

Four-terminal standard resistors forlow values of 0.1 Ω or less. These standards are used for accurate current measurements and for comparisons of low resistances. At the base and at the upper fl ange there are openings which allow air to circulate or oil to fl ow through when used in an oil bath.

• Calibration standard
• Reference measuring point in
measurement circuit
• Reference resistor in bridge circuit
• Shunt
• Maximum 200 A current in oil

  • Resistance Elements: 0.1 Ω, bifi lar wind
    ing on cylindrical brass formers with PTFE
    insulation. 0.01, 0.001, and 0.0001 ohm
    resistance material in the form of straight
    rods or loops supported on 12 mm brass
    conductors
    Terminals: Potential - Copper 4 mm
    Current - Brass
    Top Panel: Bakelite marked with the value,
    class designation and serial number

  • Case: Light alloy, black anodized to give maxi
    mum heat radiation
    Thermometer Tube: Slotted extending the length
    of the resistance element
    Label: Each standard is fi tted with a label that
    describes its characteristics and operating pa
    rameters
    Dimensions: 16 cm H x 9 cm Dia (6.3” x 3.55”)
