About Us
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 start, Van Essen’s focus was on developing water-related instrumentation. This focus never changed. In the beginning, Van Essen manufactured custom-built equipment, from single or several units to larger production batches. Over time the demand shifted to off-the-shelf products. Van Essen adapted and changed its business model accordingly.
In the early 1990s, Van Essen began to offer off-the-shelve water-related equipment such as battery-powered dataloggers using external sensors such as flowmeters for open-channel flow. Van Essen was one of the first companies to develop a tide-measuring system for the Port of Rotterdam. This system used remote monitoring, which was very advanced for its time and became a key milestone in Van Essen Instruments’ growth.
Since deploying the first Diver groundwater datalogger in 1995, Van Essen Instruments has sold over 250,000 Divers worldwide. Our commitment to quality and performance made Van Essen Instruments one of the premier brands in the industry.
Van Essen Instruments’ suite of Diver products and services is used worldwide and supported by a global distributor network of more than 60 partners in over 100 locations. We are passionate about the environment and honored to be part of projects that work to protect our precious resources. Visit the Global Sales Contacts page to find a contact near you.
