    calibrating TDS meter with distilled or deionized water

    I get you im researching those atm. what do you recommend without breaking the bank. I see bluelab and hanna the most. not trying to break the bank but im considering the quality before the price. and do those meters measure just ph or do you need a separate pen for TDS and ph?
