new to hydro need advise on this ppm/ec meter

tokenjoker78 · Jan 19, 2011

I've been doing soil for ever hydro always had like a taboo factor to me but I'm fed up with hauling dirt here and away when I'm done with it. I've decided to go with areo and have gotten everything pretty much ironed out. I've compiled all the different designs and ideas from here on RIU. My only area of confusion is with the ec/ppm meter I purchased. Ive been reading that these meters are formulated on two different values. Now I am going to apologize in advance if I make myself sound stupid. The values .500 & .700. From what I understand hydro growers want a meter that measures the ppm values on the .700 scale is this correct? Now I know i sound stupid cuz I can't think of the exact terms to call those values. anyway Im going to try to cut this short and basically all I need is for someone to tell me if the below meter will measure my nute solution accurtaly or if I should consider buying a different one
