NiCr-NiSi Type K Thermocouple Wire And Cable Ideal For Industrial Laboratory And Scientific Uses
NiCr-NiSi (Type K) Thermocouple Wire and Cable is one of the most widely used temperature measurement solutions in industrial and scientific applications. Composed of Nickel-Chromium (NiCr) and Nickel-Silicon (NiSi), it offers excellent durability, accuracy, and high-temperature performance across a broad temperature range.
Various options are available including K type thermocouple extension, thermocouple type K extension cable, duplex type K thermocouple, and shielded type K thermocouple wire, designed to meet diverse installation and environmental needs. Type K thermocouple wire connection and soldering K type thermocouple wire are essential for proper setup in systems such as MAX6675 wiring and MAX6675 Arduino wiring.
For specialized requirements, you can choose thermocouple type K glass braid insulated wire, K type thermocouple colours for easy identification, and options for K type thermocouple wire which is positive and negative. Applications often involve using K type thermocouples in extreme conditions where performance and reliability are critical.
To meet different budgets and project needs, suppliers offer competitive K type thermocouple cable price and K type thermocouple wire price based on wire type, material, and configuration.

Operates effectively between -200°C to +1250°C (-328°F to +2282°F), making it suitable for high-temperature applications.
Resistant to oxidation, corrosion, and mechanical wear in demanding environments, including high-humidity and oxidizing atmospheres.
Provides reliable and accurate temperature measurements over a wide range.
Has a Seebeck coefficient (thermoelectric voltage) that ensures sensitivity across the operating temperature range.
Positive Leg (KP): Nickel-Chromium (approximately 90% Ni, 10% Cr).
Negative Leg (KN): Nickel-Silicon (approximately 95% Ni, 2% Si, and trace elements).
Widely used with thermocouple connectors, extension cables, and measurement instruments.
Standardized by international thermocouple standards like IEC 60584 and ANSI MC96.1.
Suitable for oxidizing atmospheres, but not recommended for reducing or sulfurous environments at high temperatures.
Type K thermocouples are less expensive compared to noble metal thermocouples (e.g., Type R or S), while still offering reliable performance.
