Our customers make the highest of demands on the quality of our measuring instruments. Rightly so, because the precision of our products ensures their commercial success. This motivates us afresh each day, employees and management alike. This is how we profitably bring our decades of experience in the field of flow measurement technology to bear on a daily basis. Our technical expertise has been repeatedly attested to by external institutions. All of this enables us to approach each new challenge with confidence.

Precision across four generations
The first generation
Dosch Messapparate GmbH was founded by Adolf Dosch in 1933 with purchases from Metrum Apparatebau. Towards the end of the war, the building was hit by incendiary bombs. Thanks to the efforts of the Dosch family and their employees, the fires were extinguished and part of the building was saved. The company was forced to surrender some of its machines as reparations. Nevertheless, production was maintained as well as possible.
The second generation
The second generation, in the form of Reinhold Dosch, officially joined the company after the war and subsequently took it over together with his wife, Edda. Dosch became the first port of call for West Berlin’s industry for pressure, temperature, and flow measuring instruments. The production of differential pressure devices began in 1979. This area grew to become the company’s most important mainstay.
The third generation
Martin and Barbara Dosch joined the company in 1988. The company was first certified in accordance with ISO 9000 in 1997. Mechanical control switches for flow, fill level, and pressure extended the product portfolio from 2003 onwards. The former Laaser company’s “EARL” brand name, which was renowned for these, lived on.
The fourth generation
2016 marked the start of the fourth generation’s work at the company in the form of Sven Dosch. After obtaining his degree, he first progressed through each department and is now the second managing director alongside his father.
