Water is an essential resource in many industrial applications. High-purity water is used in specialized processes in the fields of micro electronics and pharmaceutical production. Water is also used to generate steam in power generation or industrial processes. Potable water supplied through distribution networks is a vital commodity all over the world. Continuous monitoring and controlling of the water quality in these processes as well as in the associated treatment and discharge processes is challenging. The risks and costs of insufficient monitoring are high, which calls for instrumentation specifically designed to meet the requirements of a particular application, for high reliability and low maintenance.

Swan’s success is built on a worldwide sales and support network with regional representatives, high quality products made in Switzerland and extensive knowledge in wide-ranging applications.
