Which thermocouple can be used to measure $1500^{\circ}\text{C}$ temperature?
Show Hint
Noble metal thermocouples (Platinum-Rhodium, such as Type R, S, and B) are reserved for extreme high-temperature environments.
Base-metal thermocouples (J, K, T, E) are cheaper but melt or degrade at temperatures above $1200^{\circ}\text{C}$.
