Type K Thermocouple

A Type K thermocouple is a temperature sensor made from two different metals—chromel (nickel-chromium alloy) and alumel (nickel-aluminum alloy). When the two metals are joined at one end and exposed to heat, they generate a small voltage that correlates to the temperature difference between the "hot" junction (where it measures temperature) and a reference point. Type K thermocouples are popular due to their wide temperature range (-200°C to 1260°C or -328°F to 2300°F), durability, and reliability, making them widely used in various industries for measuring temperature accurately.
