Sensor Scientiꢁc glass probe thermistors are extremely
useful in applications that require high stability and
ruggedness. The availability of 4 standard outer diameters
offers the designer the ꢂexibility to ꢁt the thermistor to the
design, rather than compromising the design to
accommodate the thermistor. The SP43A style (0.043"/
1.09mm diameter) provides the small size advantages of the
industry-standard large bead (.04±" /1.07mm) thermistor
without the associated handling problems. Typical
applications include ꢂuid ꢂow and ꢂuid level measurement,
thermal conductivity measurement, temperature
measurement, and temperature compensation.
Recommended Storage Conditions:
• Temperature 10-30 C, Humidity less than 60% RH (without dewing)
• Aꢁer unpacking, reseal and/or store product in a dry environment
• Do not store near corrosive materials or direct sunlight
