One of the keys to running an efficient, effective business is having all the right tools and parts you need to succeed. When it comes to thermocouples, it’s critical to know which types of temperature sensors are best suited for your applications. In this post, we’re highlighting a Type N thermocouple, a close relative of the common Type K thermocouple.

TYPE N THERMOCOUPLES

A quick way to describe a Type N thermocouple is as a Type K thermocouple with a few key differences. Both variants offer the same temperature ranges, with a recommended usage range of -454 to 2,300 degrees Fahrenheit. However, Type N thermocouples are made with nicrosil and nisil legs and are designed to improve on some issues found in Type K parts.

One of these improvements is a higher resistance to high temperature oxidation. While chromel in Type K thermocouples can be prone to developing “green rot” in vacuum or reduced oxygen environments with higher temperatures, Type N thermocouples can deliver accurate readings in these settings. Another advantage of Type N thermocouples is that they are better suited for nuclear environments, making them a popular option for people with related applications.

Because of their advantages over Type K thermocouples, Type N variants are the more expensive of the two parts. However, if the additional oxidation resistance and nuclear suitability is a need, it’s worth the investment.
