Tankii Group mainly produces thermocouple alloy wires, including type K , J, T, L E, N ,S, R, B
From Diameter 0.05mm to 12mm, in the form of round wire, flat wire, and enameled thermocouple wire.

What's a thermocouple?
A thermocouple consists of two dissimilar metal wires joined at one end, known as the measurement junction. When the measurement junction is heated or cooled, it generates a thermoelectric voltage that can be correlated to temperature. The other end, where the wires are not joined, is connected to the instrumentation that reads this voltage. The difference in temperature between the measurement junction and the reference point (usually at the instrument) is used to determine the actual temperature at the measurement junction.

Tankii Available types:
 

One of the factors to consider when choosing metals used in a thermocouple is the temperature range of the application. Common thermocouple types include:

• Type K: Chromel (nickel-chromium alloy) and Alumel (nickel-aluminum alloy). This type is widely used and covers a broad temperature range.
• Type J: Iron and Constantan (copper-nickel alloy). It has a more limited temperature range but lower cost compared to type K.
• Type T: Copper and Constantan. It is popular for low-temperature applications.
• Type E: Chromel and Constantan. It has the highest sensitivity and it suitable for moderate-temperature applications.

      and  Type S, R, and B (Platinum Rhodium):

These types are used for high-temperature applications, offering stability and resistance to oxidation in temperatures up to +1700°C for Type S and R, and up to +1800°C for Type B.

Positive Lead for Type S and R: Platinum-Rhodium alloy (Type S has 10% Rhodium, Type R has 13% Rhodium)

Negative Lead for Type S and R: Platinum

Positive Lead for Type B: Platinum-30% Rhodium

Negative Lead for Type B: Platinum-6% Rhodium
