HM Digital DM-2: Commercial In-Line Dual TDS Meter
HM Digital DM-2 dual in-line TDS Meter is suitable for use in industrial applications such as; Window Cleaning, Aquatics, Hydroponics, Manufacturing plus may other pure water applications where you need to monitor the TDS of two different water supplies.
The DM-2 Commercial Dual Inline TDS Meter has a stronger water resistant casing than the DM-1. This meter monitors the TDS of your reverse osmosis system in two places and displays exactly how the system is performing. We suggest installing the dual TDS meter after your membrane and before the D.I unit. These two readings will notify you when it’s time to change the R.O membrane and D.I resin.
This unit features a digital display and comes with two 1/4″ John Guest Quick Connect fittings.
FEATURES
