Type K Thermocouple provides widest operating temperature range. It consist of positive leg which is non-magnetic and negative leg which is magnetic. In K Type Thermocouple traditional base metal is used due to which it can work at high temperature and can provide widest operating temperature range. One of the constituent metal in K Type Thermocouple is Nickel, which is magnetic in nature.

Note: If the wires or the thermocouple is not color coded you can tell by using a magnet. The negative wire will be magnetic, and the positive wire is not.

Here we offer a range of high temperature ceramic k-type thermocouples. These very high temperature k-type thermocouple can measure up to 1260 °C or 2300 °F.
A high temperature K-type thermocouple can be uses with your ceramic kiln, glass fusing kiln, high temperature  furnace, metal melting furnace, high temperature ovens, for your forge, crucible or other metal working setup.

6 inch thermocouples are ideal and interchangeable with most kilns. Thermocouples are made of two types of wire. The temperature is read from the thermocouple probe's tip that is inside the kiln and where the two different wires meet.

Temperature Range : –454 to 2,300 deg F (–270 to1260°C)
