i've found 2 different types of hanna combo meters on ebay and one of them is a monitor and the other is just a tester. the monitor keeps CONTINUOUS track of the tds/ec and ph levels but the tester just tells you what the measurements are at that certain period but it does float. does it matter which one i get? is one better than the other? i was thinking of just getting the tester bcuz it is cheaper but i dont wanna skimp out and mess up my whole grow bcuz i know that tds and ph are very important. does any one have any input on this matter? should i get the monitor (more expensive) or the tester (better price range 4 me)????????????
