History

The company was founded in 1924 by Lieutenant Lodewijk Wittich and Governor Piet Visser and is since then specialized in scientific instruments and systems for meteorology.

In 1898 Lt. Lodewijk Wittich was retired at the age of 40 years from the K.N.I.L army in the Dutch East Indies. Three times he was decorated among which with the military “Willemsorde”. He settled in The Hague and on 1 January 1899 he started a company in sports articles, military materials (targets, pocket knives) and scientific instruments (stereoscopes).

The Visser family settled in The Hague and became neighbours with Wittich. This resulted in a partnership as they founded the company Wittich & Visser in 1924. From this moment on, the company is focused on scientific and meteorological instruments.

Since 1926 the company is exclusive representative for the renowned Berlin instrument factory Rudolph Fuess. Important clients were weather service old wind vaneKNMI, military, textile industry and charcoal mines. Some of these industries are disappeared but the interest in and need for scientific and meteorological measurements increased over the years.

Nowadays we have systems for surface measurements, boundary layer and upper air. Remote sensing profilers based on radar, ultra sound, sound beams, microwave, scintillisation of light, infra red, lyman alpha etc. Our instruments are applied in: scientific research, military, building automation, green house automation, weather observers etc.

Calibration & service

Most weather sensors need calibration and maintenance on a regular basis to maintain an optimum performance. Wittich & Visser offers calibration devices and accessories for all probes. We can also calibrate your probes for you. We have a reminder service to help you remember that your instruments need calibration and maintenance.
