Platinum rhodium thermocouple wire is a type of thermocouple used for temperature measurement in high-temperature applications. It consists of two wires made of different metals, platinum and rhodium, which are joined together at one end to form a measuring junction. The other ends of the wires are connected to a measuring instrument, such as a thermometer or temperature controller. Platinum and rhodium are chosen for this type of thermocouple because they have a high melting point, are resistant to oxidation and corrosion, and have good stability and reproducibility over a wide temperature range. The combination of platinum and rhodium is particularly useful for measuring temperatures between 0°C and 1600°C.
