Temperature Range:
Standard: -270°C to +1300°C (-454°F to +2372°F)
Short-term: Up to 1400°C (2552°F)
Accuracy:
Standard: ±2.2°C or ±0.75% (whichever is greater)
Special Limits of Error (SLE): ±1.1°C or ±0.4%
Advantages:
Better oxidation resistance than Type K (less drift at high temperatures).
Good stability in oxidizing atmospheres.
Less prone to green rot (a degradation issue in Type K).
More accurate than Type K at high temperatures.
