Founded in Delft, Netherlands, with offices in the US and Canada, Van Essen Instruments has served for over 80 years as a world leader in the development, design, and manufacture of groundwater and surface water data acquisition technology with its line of Diver dataloggers that monitor ground water levels, conductivity, and temperatures in an effort to reduce municipal groundwater monitoring costs, improve data quality and achieve greater insight into groundwater resources.

Van Essen’s groundwater dataloggers provide long-term measurements of water levels, temperature, and conductivity — essential data for effective water resource management, environmental remediation, mine dewatering, and slope stability. Its groundwater monitoring network technology integrates superior field instrumentation with the industry’s latest wireless communication and data management capabilities to streamline project workflows and enable users to effectively manage groundwater resources over the long-term.
