What is Thermocouple ?

A thermocouple is a sensor for measuring temperature. This sensor consists of two dissimilar metal wires, joined at one end, and connected to a thermocouple thermometer or other thermocouple-capable device at the other end. When properly configured, thermocouples can provide temperature measurements over wide range of temperatures.

Temperature Ranges for Type K & J Thermocouples

Type K & J thermocouples have a general temperature range of -200 to 1260°C (-326 to 2300°F), however there are some caveats to this:

If used for temperatures below 0°C special material is needed in order to meet the specified accuracies. Also, Special Limits of Error are not specified for temperatures below 0°C.
The ultimate suggested upper temperature limits for Type K & J are based on the size of the conductor used:

How Much Do Thermocouples Cost?

The cost of a thermocouple will depend upon the style and type of the sensor you choose. Once you determine what style sensor you need you can contact us for quotation.
