Frequently Asked Questions (FAQ)
When measuring temperatures between 350 and 540°C with a K thermocouple, the measured value is several degrees higher than the actual temperature, but when the temperature reaches 600°C or higher, the correct temperature is display within a few seconds. Is there any reason for this?
Short-range ordering may be the cause of K thermocouples fluctuating around 350 to 540°C. It is known that K thermocouples change state between 250°C and 550°C, causing the electromotive force to become unstable. This is resolved above 600°C. When measuring around this temperature range, we recommend using T or J thermocouples.
