0.5″ 12.7mm KP Chromel KN Alumel Thermocouple Type K Rod Application

The characteristic of Type K is that it has strong anti-oxidation performance, and should be used continuously in an oxidizing and inert atmosphere. The long-term use temperature is 1000℃ and the short-term 1200 ℃. It is the most widely used among all thermocouples; (it cannot be used reducing gas atmosphere).
