Inline Dual TDS Meter, DM-1 TDS Monitor

Measure the TDS of tap water coming in vs. the purified water going out of your system at any time. Use the monitor to determine when the filters need to be changed. Install the meter for your customers so they'll always know how their system is performing.

Dual TDS Monitor is a vital part of any RO/DI system. It plays a major role in ensuring that your system is performing at it’s best and continues to do so. It will alert you to when it is time to replace RO membranes and DI resin.

Inline TDS Meter measures the tap or any other water source such as water coming out of your purification system for TDS, Total Dissolved Solids. Ideal for testing the effectiveness of Reverse Osmosis systems. Measures Total Dissolved Solids (TDS) in water.

The HM Digital DM-1 TDS Reader provides an easy to read dual line TDS monitor that provides a digital readout. It is ideal for any water filtration system, including reverse osmosis systems, watermakers, DI filter, coolers and much more.
