INOR Process AB is a Swedish manufacturer of industrial temperature measurement equipment, founded in 1939 in Malmö. In 1974, the company introduced the world‘s first temperature transmitter that could be mounted directly inside a sensor connection head—a design that later became an industry standard. Today, INOR produces the IPAQ series of head-mounted and DIN-rail temperature transmitters, board-level OEM modules, IsoPAQ signal isolators and converters, and SR series temperature monitoring relays. The company’s products are certified to ATEX, SIL2, and HART 7 standards for demanding process applications. INOR operates under ISO 9000 and ISO 14001 certified management systems at its Malmö facility. After nearly two decades as part of the KROHNE Group, INOR was acquired by WIKA Group in 2025.
