1974 – World’s first head-mounted temperature transmitter

The TRA-R1 from INOR was the world’s first head-mounted temperature transmitter
TRA-R1

INOR expanded over time and started assembly of instruments and service. In the sixties INOR decided to develop their own temperature transmitter. This development led to a major breakthrough in 1974 when INOR invented and developed 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 and INOR is today a well renowned brand name all over the world.

One of INOR’s first self-produced measurement instruments, an optical pyrometer for temperature measurement in melting furnaces.
