Van Essen Instruments was founded in 1938 by Cornelis van Essen in Delft, Netherlands. Cornelis was an electronics engineer by profession and had an interest in the development of instrumentation. 

From the beginning, Van Essen Instruments’ focus of developing water related instruments never changed. In the beginning, Van Essen produced customer specific equipment: sometimes only one, or sometimes just a small production batch of 5 units,  but due to a demand of standardizing products, especially in the electronic and mechanical domain, Van Essen decided to adapt and change the business model.

In the early 1990s, Van Essen began to offer standard water related equipment such as standalone dataloggers, which used external sensors and flow meters for open channels. Van Essen was one of the first companies to develop a tide measuring system for the Rotterdam Harbor. In this project telemetry was used. Telemetry was very advanced for its time and became a key milestone in Van Essen’s growth.

Since the deployment of the first Diver, Van Essen Instruments have sold over 200,000 dataloggers worldwide. Our commitment to quality and performance has established Van Essen Instruments as one of the premier brands in the industry.

Van Essen Instruments’ suite of Diver products and services are active in countries around the world, and supported by a global distributor network of more than 60 re-seller partners in over 100 locations. We are passionate about the environment and honoured to be part of projects that work to protect our precious resources.
