Thermocouple Type K: Type K (Chromel®–Alumel®) is the most common general-purpose thermocouple. It is inexpensive, and a wide variety of probes are available in its −200 °C
Thermocouple Type N: Type N (Nicrosil/Nisil) thermocouple has a Nicrosil (nickel-14%, chromium-1.5%, and silicon) positive leg, and a Nisil (nickel- 4.5%, silicon-1%, and magnesium) negative leg.
Thermocouple Type R: Types R thermocouples, (Platinum vs. 13% Rhodium/Platinum), are usable up to 1480°C (2,700°F). They are extremely stable but reducing atmospheres are particularly damaging.
Thermocouple Type S: Platinum/10% Rhodium positive leg, and a pure platinum negative leg. The temperature range for Type S is 0 – 1450°C (32 –
Thermocouple Type T: Type T (Copper-Constantan) thermocouples are suited for measurements in the −200 to 350°C (-330 to 660°F) range. They are often used as a
When installing sensors in a hazardous area, there is a requirement to install a sensor that is suitable and approved for use in that hazardous
Thermowells are recommended whenever a temperature element is to be inserted into a process where corrosion, pressure, abrasion, or shear forces may threaten the life

Rare metal thermocouples are used in applications where the temperatures exceed the working range of base metal thermocouples, i.e. 0â€1300°C, or where greater accuracy is
Temperature is one of the most important units of measurement that industries monitor. It is extremely imperative that temperature be as accurate as possible. If
