Expendable Thermocouple
Immersion Disposable Thermocouples are used to measure the temperature directly, precisely and
instantly through immersion method, in the production & refining of iron, steel & other ferrous and
non-ferrous in Electric Arc Furnaces, other melting furnaces, LD converters, Ladles, etc and for the
chemical analysis of the metal during its manufacturing stage. It is a simple and cost effective
instrument and provides the quickest way to get the most accurate readings. To measure the
temperature, the thermocouple is connected to the coupling lance. Which contains the polarized
contact block.

Thermocouple Parts
• Protection cap : The thermocouple cap is part of the "Disposable Immersion Thermocouple". It
