We manufacture type N thermocouples to your specifications or as replacements to existing sensors. We have manufactured thermocouples for over 15 years and are solely focused on the design and manufacture of temperature sensors. Please call or email us to discuss your requirements.
Type N Thermocouple Designs
Thermocouples can come in a variety of designs suited to different applications. View the details of each type of design we offer for Type N.
Type N Inserts – Rigid metal tubes commonly used in pocket, thermowell or head assemblies.
Type N Elements – Basic elements for further assembly into sheaths or equipment.
Thermocouple Type N Technical Details
Type N is a relativity new thermocouple type that was made to be an alternative to Type K. It has high stability over time but is more costly than type K at similar temperature ranges. Its sensitivity is about 39 µV/°C, slightly lower compared to type K.
