I use this every time i make RO/DI water. Its an easy way to tell if I have to change my filters.
Great TDS Monitor By Corbett on 3/22/10

I monitor the TDS of the water through my RO/DI at 3 points: straight out of the tap, after the RO membrane, and the final product water after the DI resin. The dual monitor is a better value than this single monitor (so this gets 4 stars on value), but since I like to monitor at three different points in my process, I need one of these in addition to a dual monitor and it works perfectly to ensure that my water is pure.
