RS PRO Type J Heavy Duty Thermocouple 150mm Length, 4.5mm Diameter → +350°C

Heavy Duty, Type J & K Thermocouples

Type K & J Thermocouples is a device which measures temperatures, it’s made up from two wires which are different materials. When these two wires are joined together, they create an electrical junction. Once the temperature changes at this junction, it created a voltage which can then be interpreted and read as a temperature. This is commonly known as the “Seebeck Effect”.

Types of Thermocouples

• Type K Thermocouples: Type K is one of the most common types of thermocouple. They’re popular due to their low cost, the Type K are accurate, provide reliability and have a wide temperature range.
• Type J Thermocouples: Type J is also very common and widely known for their low cost, good performance and reliability. Can hold its own in higher temperature ranges, but this can shorten its lifespan.
• Type T Thermocouples: Type T offers stability and consistency, you can typically expect to use type T in exceptionally low temperature situations - such as freezing.
• Type N Thermocouples: Type N shares similar accuracy and temperature limits as Type K. Type N is slightly higher in their price range.
• Type L Thermocouples: Type L specialise in measurements of liquids such as liquid metals. They’re commonly used in heating and apparatus engineering. This type of thermocouple is also cost effective, efficient and reliable.
