The Watermark sensor is the standard sensor in urban green and landscaping. Watermarks are maintenance-free, inexpensive, frost-proof and buffered against the fluctuating salt content of the soil solution. The sensors have a measuring range from 0 to 239 kPa soil water potential. Data interpretation is simple and transferable from site to site, as the measurement result is output as a soil water potential value. The technology is accurate, durable and has been tried and tested in practice for decades.

MMM tech support GmbH & Co KG is the general distributor for Watermark sensors in Germany and Central Europe.
