Dual Inline Digital TDS Meter
The Dual Inline TDS Meter is ideal for monitoring the quality of water being produced by an RO or RO/DI System.
The Dual Inline TDS Meter also allows you to monitor the condition of a Reverse Osmosis Membrane or Mixed Bed Resin, by comparing the TDS level of water before the system and after. For example, if there is little to no difference between the TDS level of the source water, compared to that of the "product" water then it means the membrane and/or mixed bed resin needs to be replaced.
