I purchased 3 part nute system from advanced nutrients. Alot of these meters are pricey but they say well worth it. What do you all use to keep your nutrient to volume of water accurate. What is a good meter for a beginner that is easy to understand and is accurate. I am growing Hydropnically.

Thanks Folks!
FYI...Advanced Nutrients 3-part is a copy of GH 3-part.

Next. get milwaukee meters...you won't be sorry...I got both mine off ebay...I use a milwaukee ph pen and a milwaukee sm-301 smartmeter (EC)
I have had them both over a year almost 2 and no problems. My local hydro store dealer told me he switched to milwaukee exclusively and avoids Hanna at all costs. He claims hanna has terrible customer service.
