Thermocouple can be connected directly to digital thermometers.
By removing its connector, it can also be connected to temperature controllers.
It can measure VERY HIGH temperatures up to 2372 °F(1300°)
You can adjust the length of this thermocouple by bending the probe/thread at installation.
To use the thermocouple, I recommend placing the probe under the metal
as it sits in the forge. This will give the most accurate reading.
Typical use is to learn the correlation between temp and color. After
a while, you will no longer need the thermocouple except for HT.
