The ST-200 is an accurate (± 0.2 C from 0 to 70 C) fine wire (0.45 mm tip, 0.15 mm wire) thermistor designed for measurement of delicate surfaces or small samples with a fast response time, less than 1 second.

Measurement Range    -50 to 70 C

Measurement Uncertainty    0.2 C (from 0 to 70 C), 0.4 C (from -50 to 0 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)
