Most widely use thermocouple wire Type K model

TYPE K (NiCr vs NiSi ) is used in oxidizing, inert or dry reducing atmospheres. Exposure to vacuum limited to short time periods. Must be protected from sulfurous and marginally oxidizing atmospheres. Reliable and accurate at high temperatures. 

Senphus mainly thermocouple type and relative advantages

K Type: NiCr-NiSi 

Type K thermocouple has strong resistance to oxidation than other base metal thermocouples. It has high EMF against Platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost. It is recommended for oxidizing or inert atmospheres, but cannot be used directly in the following cases:

1. Alternatively oxidizing and reducing atmosphere

2. Atmosphere with sulphur gases

3. Long time in vacuum

4. Low oxidizing atmosphere such as hydrogen and carbon monoxide atmosphere

N Type: NiCrSi-NiSiMg

Type N thermocouple improves the EMF drift and short term EMF change, compared to type K thermocouple, and has a longer life than type K thermocouple. Therefore, in the industries where temperature control and measurement are especially critical, type N thermocouple has more advantages than other thermocouple as it has long life and stable thermal EMF.

J Type: Fe-CuNi

Type J thermocouple has good resistance to oxidation and high EMF output against Platinum 67, with good temperature accuracy, sensitivity and stability. It is recommended for vacuum, oxidizing, reducing or inert atmospheres, but it can not be used in sulphrous atmosphere above 500℃.

E Type: NiCr-CuNi

Type E thermocouple has the largest EMF output and highest sensitivity, so it is ideal for measuring small temperature change. It also has good stability in the low temperature range up to 300°C, and good property of anti-corrosion in humidity atmosphere. It is recommended for oxidizing or inert atmospheres, but cannot be used directly in reducing atmosphere and atmosphere with sulphur gases.

T Type: Cu-CuNi

Type T thermocouple has good resistance to oxidation, high EMF output, with good temperature accuracy, sensitivity and stability. In the temperature range -200~0℃, it has better property, the year stability is less than ±3μV.
