any digital meter will work. look to spend $40-100 though. do a search of ph meters on RIU. the top 2 manafacturers are hanna, and oakton IMO but are easily $80+. if you have the money i would get a PH,EC combo meter $130+. ull get a better deal online prob though. you can get a decent ph pen on ebay for $25 shipped. but remember you get what u pay for. if you have the funds i would get a nice 1 now. since youll end up getting one(or should) in the future.
