In 60% of the European cities with more than 100,000 people, groundwater is being used much faster than it can be replenished. At the same time, aging water networks systems waste more than 40% of water supply through leaks and cracks.

HM Digital

HM Digital is recognised around the world for providing water testing equipment. The TDS (Total Dissolved Solids) meter tests for charge ions, including minerals, salts or metals dissolved in a given volume of water.
