thanks i was just lookin to buy one of those, is here a specific model you recommend?

any of those would be just fine. after 2 years, i wore out a hanna 3n1 combo. so the last time i ordered 2 of the cheap ph1 meters (one for a spare) and am getting great service out of it. i did notice they have a really good price on the combo also. i still use my combo for tds.

are these tds/ec meters only for hydro?
