Maltec-T Type K Thermocouple

Chromel { 90% nickel And 10% Chromium }
Alumel { 95% Nickel, 2% Manganese, 2% Aluminum And 1% Silicon }

This is the most common thermocouple type that provides the widest operating temperature range. Type K thermocouples generally will work in most applications because they are nickel based and have good corrosion resistance.

1.Positive leg is non-magnetic, negative leg is magnetic.
2. Traditional base-metal choice for high temperature work.
3. Appropriate for use in oxidizing or inert atmospheres at temperatures up to 1260°C (2300°F).
4. Vulnerable to sulfur attack (refrain from exposing to sulfur-containing atmospheres).
5. Perform best in clean oxidizing atmospheres.
6. Not recommended for use under partially oxidizing conditions in vacuum, or when subjected to alternating cycles of oxidization and reduction.

Due to its reliability and accuracy the Type K thermocouple is used extensively at temperatures up to 2300°F (1260°C). This type of thermocouple should be protected with a suitable metal or ceramic protection tube, especially in reducing atmospheres. In oxidizing atmospheres, such as electric furnaces, tube protection is not always necessary when other conditions are suitable; however, it is recommended for cleanliness and general mechanical protection. Type K will generally outlast Type J because the JP wire rapidly oxidizes, especially at higher temperatures.

Type K thermocouples are used for measurements in many different types of environments such as water, mild chemical solutions , gases and dry areas. Engines, oil heaters and boilers are examples of places where they may be found. They are used as thermometers in hospitals and the food industry. Its capability to function in rugged environmental conditions and in various atmospheres makes it a preference over other temperature transduction devices.
