Reference standard Type ‘R’ & ‘S’ thermocouples are made from High purity
reference grade platinum and platinum rhodium alloy. It covers Temperature
range up to 1500°C. It is commonly used as reference standard to calibrate
Industrial thermocouples. This sensors are assembled with 6mm OD, 450mm or
600mm long gas tight 99.7% high Alumina sheath. This type thermocouples,
besides the low ageing drift, also offers the advantage of a low basic tolerance
value. This model with Cold Junction compensation probe provides much accurate
temperature measurement possibilities, The Cold Junction probe is inserted in to
ICE water mixture. This is necessary for the Precision measurement.
