Water quality monitors measure and regulate electrical conductivity (EC) and total dissolved solids (TDS) in the water supply. In-line monitors have extended measurement ranges and easily attach to your current water supply line. Measuring TDS levels in your tap (feed) water and purified (product) water, as well as waterflow and volume, helps you determine the safely of your water.
