The Type R / Type S reference thermocouple was specifically developed as a temperature standard for industrial calibrations and temperature measurements. It consists of the same high quality thermocouple material as the Type R / Type S precision thermocouple. However, the design of the Type R / Type S reference thermocouple is specially adapted to industrial requirements. For example, the ceramic sheath is made from a smaller protection tube. These small dimensions mean that the Type R / Type S reference thermocouple can be used as a temperature standard for calibration with dry block calibrators, for example. As a further adaptation to industrial conditions, an external reference junction can optionally be dispensed with; instead, Type R / Type S mini plugs can be used. Excellent measurement uncertainties are achieved with this type of thermometer, as no compensating materials are used if required (not even on the connecting cable).
