Cheap TDS/PH meter?
go to eBay.... search for E/C or TDS meter around $30
keylime Reviewed by keylime on . Cheap TDS/PH meter? Anyone know where to get (online) a relatively cheap TDS and PH meter? ~40-50$ each? Local hydro store wanted 70$ for PH and 110$ for TDS!!! Hannas seem to be what people go with, but they are pricey! thanks. Rating: 5
