Thermowell Material Guide

Thermowell materials for various average applications are listed in the following table. The list has been carefully prepared and takes into consideration such factors as contamination, electrolysis, catalytic reaction and other variables. Standard materials are recommended wherever possible. Service may vary, however, in industrial use as a result of temperature, pressure, concentration and impurities in the corrosive medium.

While the recommendations cannot guarantee service, they will serve as an effective guide. Thermo Sensors Corporation can provide consultation for special applications upon request.
