INOR - Temperature Measurement

Specialists in industrial temperature measurement

INOR was founded in 1939, and with 75 years experience of industrial temperature measurement, our company possesses an incomparable level of expertise. From the beginning being one step ahead has always been our goal. This means continual development of both our company and products.



In 1974, INOR introduced the world’s first head-mounted transmitter. The head-mounted temperature transmitter has since then turned into an international standard. The heritage of this has continued with more own-developed high quality transmitters including ATEX and SIL2-certified transmitters to transmitters with Profibus or HART communication. Regardless of what type of temperature sensor you are using in your process, INOR can provide a transmitter that suits your needs.
