Why use a handheld TDS meter when the DM-1 can be permanently installed on your reverse osmosis or deionization system. A quick glance at the LCD and a flip of the switch will give you both your incoming and outgoing TDS readings. Don't guess when your membrane or DI resin needs to be replaced. Purchase the DM-1 and know when your TDS has reached unsatisfactory levels.
