The tendency of Platinum and rhodium alloy is little than pure platinum crystal length, and decrease with increase of platinum, can make the thermoelectric performance more stable and the mechanical strength higher. Therefore double platinum and rhodium thermocouple has been widely used in 1800 degree heat measurements. Thermocouple indexing no of thermocouple used to be LL-2, now is B. Platinum and rhodium 30-platium and rhodium 6 thermocouple indexing table (indexing No: B) (Reference terminal temperature: 0°C) thermoelectric power: mv
