Interchangeable and Point Matched Thermistors Icon_RedArrow_Down

Features:

mini_rtd

Interchangeable thermistors have tight tolerances guaranteed to track a specific resistance temperature (R/T) curve over a temperature range. Point Matched thermistors are tested at a given temperature and guaranteed to be within a specified percentage of the nominal resistance at that temperature. Our point matched thermistors can guarantee that you'll be able to receive the accurate temperature measurement you need for your work. Feel free to browse our other sensor components to see if there are other products you need.
