TDS meters can are helpful for brewing if you’re using a RO filter or if you purchase RO (reverse osmosis) or distilled water for brewing.  If you’re using and 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 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.
