NiCr-NiSi Type K Thermocouple Wire And Cable Durable And Versatile For Industrial And Scientific
NiCr-NiSi Type K Thermocouple Wire and Cable is a widely used thermocouple material for temperature measurement applications. It is composed of a positive leg made from Nickel-Chromium alloy (NiCr) and a negative leg made from Nickel-Silicon alloy (NiSi). Type K thermocouples are known for their broad temperature range, reliability, and resistance to oxidation. NiCr-NiSi Type K Thermocouple Wire and Cable is an economical, durable, and reliable choice for high-temperature measurement applications. Its wide temperature range, resistance to oxidation, and availability in various forms make it a versatile tool for industrial and scientific applications.

Operates effectively in a range of -200°C to 1260°C (-328°F to 2300°F), suitable for both low and high-temperature environments.
Provides accurate and reliable temperature measurements with a standard tolerance of ±2.2°C or ±0.75% of the measured temperature.
Performs well in oxidizing atmospheres due to the high chromium content in the positive leg.
Suitable for use in inert or oxidizing environments but not ideal for reducing or sulfur-containing atmospheres.
Designed for durability and long service life, even in high-temperature applications.
Produces a stable thermoelectric voltage (Seebeck coefficient) of approximately 41 µV/°C at 1000°C.
Positive Leg (NiCr): Typically 90% Nickel and 10% Chromium.
Negative Leg (NiSi): A combination of Nickel, Silicon, and small amounts of Manganese or Aluminum.
