90 years REO

… with tradition, innovation, and technical expertise in the future

The company Haase & REO was founded on 17.08.1925 in Berlin by Boris Reichsfreiherr von Wolff.
In the following years, resistors for testing instruments and ballasts for arc lamps were produced. At that time adjustable resistors – whether rheostats or potentiometers – were much sought-after and necessary products in order to ensure the advancement of the electrotechnical age.
