DEIF (Danish Electro Instrument Factory) was established in 1933 by Erling Foss and his two partners. The company’s main activity consisted in assembling and mounting by hand basic electromagnetic measuring instruments. Focus was on precision and robustness.

Today, DEIF is owned and managed by the founder's son, Toke Foss. The products have become extremely more advanced and markets now include knowledge intensive business areas such as Engine & Genset Controls, Switchboard Instrumentation, Bridge Instrumentation and Renewable Energy Controls. Yet, the focus on quality, reliability and service remains the same.

Production and development are located in Denmark, but DEIF sells and services its products worldwide.
