Description
TDS-3 is the most widely used handheld TDS meter in the world for hand held testing of TDS, the contaminant removed by the Reverse Osmosis (RO)Membrane itself. The TDS-3 Meter can be used to test membrane effectiveness, as well as DI Resin performance. This meter can be used to measure the effectiveness of the membrane. To perform a test on a membrane (2) samples must be drawn. The first is untreated water and the other is RO treated water. Use the TDS reading to calculate a removal ratio. MERO Thin Film Composite (TFC) Membranes are effective for 95-98% removal of TDS when new. Replace at 85% removal. This meter can also be used to test the DI Resin performance. Water exiting the DI Resin should have zero TDS. Replace DI as this number rises.
