How to use TDS meter.

TDS reading test should be taken both for source water sample and purified water sample. 

TDS reading test should to be taken not earlier than 4-7 days after new RO use (or pass 30-50 gallons of water). If you change filters for new ones, wait at least 4-5 days until take reading test. The carbon dust (fullt unharmful from new carbon filters) still in new filters for couple of days even water looks clear. 


Taking TDS reading from Countertop RO.

TDS reading test samples can be taken from diverter if your RO system has only T33 Carbon post filter, DI or DI/T33 post filter(s). Any mineral / alkaline / calcite / KDF-55/85 filter cartridge adds some minerals back into water which causes significant raise of TDS level. This TDS comes from the "good" minerals. To check how your RO system performs, we need to eliminate this "good" TDS data. So  take water samples from tubing coming right after membrane outlet.  Disconnect membrane stage and the stage right after membrane to collect 2-4 oz of water sample. Check TDS reading. Reconnect membrane housing to the next stage back. You can check this manual : https://www.reverseosmosisrevolution.com/images/brokenfitting.pdf (page #8).
