INTERTEC is a supplier of unique systems designed to provide reliable protection of sensitive field-mounted instruments. The company was founded in 1965 by Dr.-Ing. Joachim Hess, who recognized the problem of inadequate protection of electronic instruments in the field of engineering. Neglect or failures in instrument protection, however, can seriously affect plant safety and the operation of the complete system. Even operating and maintenance costs can be reduced considerably by providing adequate instrument protection.
