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
