These are S – Type Thermocouple sensor with Cold Junction. This range is based on special Reference thermocouples for high temperatures upto 1200°C for highly accurate temperature measurement. These Thermocouples are offered in platinum / Rhodium (type R, S or B) elements with a high purity Alumina insulations and sheath materials. The Cold junction compensation probe provides much accurate temperature measurement possibilities. The cold junction probe is inserted into Ice water mixture. This is necessary for precision
measurement.
