We have written it in the instruction manual.
・ There are differences depending on the usage situation and the surrounding environment every 2500 hours
from the start of operation and 2500 hours after

- What is the difference between [J type] and [K type] thermocouples?
Thermocouples (thermocouples): There are more than 10 types, but the ones used for extruders are mainly [J type] and [K type].
Thermocouples connect the tips of two different types of metal wires to form a circuit, and measure the temperature difference through the “thermo-electromotive force” generated at the contacts. The difference between [J type] and [K type] of thermocouples is that the type of metal is different and the measurement temperature range is also different.
