Dual Inline TDS Meter DM-1

This HM Digital DM-1 TDS meter can be used to test the quality of water from two different water inputs by detecting the TDS (Total Dissolved Solids) in the water and displaying this as a reading of how many PPM (parts per million) of total dissolved solids there are in the water.

Simply connect the supplied tee fittings in-line with the water pipe to read the TDS, for example one could be connected to the incoming water to an RO system, and one to the outgoing water, allowing you to observe the difference in water quality between the two points.

Ideal for testing the water quality of your tap water, water filter, hydroponics, agricultural water, colloidal silver, or for testing Reverse Osmosis or De-ionized water for use with dental sterilization equipment or window cleaning.
