The ST-100 is a high accuracy thermistor (± 0.1 C from 0 to 70 C), mounted in a waterproof housing, designed for continuous measurement of air, soil, or water.
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)
Equilibration Time 30 s
Self-Heating Less than 0.01 C (typical, assuming pulsed excitation of 2.5 V DC), 0.08 C at 5 C (maximum, assuming continuous input excitation of 2.5 V DC)
Operating Environment -50 to 70 C, 0 to 100 % relative humidity
Resistance at 0 C 32651.0 Ω
Input Voltage Requirement 2.5 V DC excitation
Output Voltage Range 0 to 2.5 V DC (assuming input excitation of 2.5 V DC)
Current Drain 0.1 mA DC at 70 C (maximum, assuming continuous input excitation of 2.5 V DC)
Dimensions 70 mm length, 6 mm diameter
Mass 60 g
Cable 5 m of shielded, twisted-pair wire with santoprene rubber jacket (high water resistance, high UV stability, flexibility in cold conditions)
Warranty 4 years against defects in materials and workmanship
