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.
