HM Digital DM-1, Dual Inline TDS Meter for RO Systems

DM-1: In-Line Dual TDS Monitor

A TDS Monitor measures the amount of Total Dissolved Solids (TDS) in a solution.

The DM-1 is consumer friendly monitor measuring feed (input) water vs. product (output) water of a water filtration system at any time. This device is ideal for Reverse Osmosis (RO), Deionized water (DI) filtration systems that work well in variety of application such as drinking or potable water, Aquariums, Hydroponics and many more.
