From the Managing Director

Thank you for visiting our website. Xylem Analytics UK is in the perfect position. We are able to supply cutting edge, innovative technology, like our new Seaguard, Ecomapper, Castaway and Riversurveyor products and match them with application specialists, based locally in the UK. This gives customers quick access to the newest product developments and ensures there is back up and service available at all times.

A demand for easier to use sensors, easily accessed data and lower cost of ownership has focused our research and development efforts. The result is a stream of new products and concepts. We are always open to ideas on products from our users, and we always welcome the opportunity to provide back up and service to you.
