Product Description

Standard: ASTM E230

NiCr-NiSi thermocouple finds the widest use in all base metal thermocouple, at temperature above 500°C

The main chemical composition of positive leg NiCr (KP) are Ni≈90% and Cr≈10%, negative leg NiSi (KN) are Ni≈97% and Cr≈3%

The operating temperature range is -200-1,300°C (for short term) and 0-1100°C (for long term)

Type K thermocouple has strong resistance to oxidation than other base metal thermocouples

With high EMF against platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost

Recommended for oxidizing or inert atmospheres, but cannot be used directly in the following cases:

Thermocouples wire (class 1, and 2):

Type B (Pt-30Rh Vs Pt-6Rh) thermocouples wire

Type R (Pt-13Rh Vs Pt) thermocouples wire

Type S (Pt-10Rh Vs Pt) thermocouples wire

Type K (Ni-10Cr Vs Ni-3Si) thermocouples wire

Type E (Ni-10Cr Vs Cu-45Ni) thermocouples wire

Type T (Cu Vs Cu-45Ni) thermocouples wire

Type J (Fe Vs Cu-45Ni) thermocouples wire
