LOW TEMPERATURE CALIBRATION FACILITIES AT KRISS

• Abstract:

  We review the low temperature calibration facilities at the Korea Research Institute of Standards and Science. For the calibration of capsule-type standard resistance thermometers, open and sealed cells of cryogenic fixed points and their realization system were manufactured and used. A sealed cell of the triple point of Argon for long-stem standard platinum resistance thermometers was also manufactured. For calibration by comparison, a controllable comparison cryostat and a nitrogen boiling point temperature block were made. We also review our traceability scheme and supporting international key comparisons for the dissemination of low temperature standards.
