Ice-cooled reference junction temperature compensator UN

The UN is an ice-cooled reference junction temperature compensator that maintains a reference junction temperature of 0°C by placing ice fragments inside a Dewar flask within the main unit, burying the thermocouple in the glass tube.

For high accuracy performance testing of thermocouples

  • Maintain the inside of the Dewar bottle at 0°C.
    By utilizing the property that the interface between ice and water is 0°C, finely shaved ice pieces are placed inside a Dewar flask (thermos).
    By filling the inside uniformly, it is possible to maintain the temperature inside the bottle at 0°C.
  • Design with excellent heat conduction and stability
    The thermocouple is placed in a glass tube, and its tip is filled with silicon glass.
  • A stick-type alcohol thermometer is included for reference.
  • If there are two or more input points, a wooden box to support terminal board is included.
