Current Stock:
Measurement Range
-50 to 70 C
Measurement Uncertainty
0.1 C (from 0 to 70 C), 0.2 C (from -25 to 0 C), 0.4 C (from -50 to -25 C)
Measurement Repeatability
Less than 0.05 C
Non-stability (Long-term Drift)
Less than 0.02 C per year (when used in non-condensing environments where the annual average temperature is less than 30 C; continuously high temperatures or continuously humid environments increase drift rate)
