Usually PPM meter and EC meter are one in the same. Push of a button to change the display. Mine is from Hanna and also reads PH. You won't feel like checking this stuff all the time but it is the only way to really know what is going on with your system. A worthwhile investment no doubt.
CaliJay Reviewed by CaliJay on . Somebody Please Explain..... I have been reading alot about EC, PPM, TDS meters but still dont quite have a good understanding on which meter would be right for me. I have read that PPM and EC basically read the same thing but you have to use conversion/mathematics. I will have a simple system 4 plants max fed from a 10 gal res. 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.
