Fast, Accurate, Repeatable Temperature Measurement

Watlow thermistors are designed to ensure fast, accurate and repeatable temperature measurement. Thermistors are highly sensitive to small changes in temperature and maintain accurate temperatures over a limited range. These sensors are made with either epoxy-coated or glass-coated constructions and can be used in the most demanding environmental conditions.

Features & Benefits

Designed to maintain accuracy over the life of the sensor improves process control

High resistance reduces the chance for errors

Interchangeable maintains good system repeatability

Point sensitive senses temperature in a very specific location


Optical Res Accuracy Temperature Outside Diameter
± 1% at 77°F (25°C) to ±15% at 32°F (0°C) -75 to 500 -60 to 260 In Cm
