TDS meters can are helpful for brewing if you’re using a RO filter or if you purchase RO (reverse osmosis) water for brewing.  If you’re using an RO filter a TDS meter tells you how effective your filter is and can help you know if your filters need to be replaced.  If you buy RO water, a TDS meter can let you know what you’re getting as some water processors add minerals back for flavor.  A TDS meter will allow you to make sure you’re getting what you want.

I have this meter and it works great.  I use it in coordination with my RO filter [Review – some pictures of this meter are in that review] to test filter effectiveness.

RO water can be built up to reflect the exact water profile you’re looking for.  See: Water by John Palmer and Colin Kaminski
