Which one of these meters should I get?

So I'm looking to pick up a pH/EC meter and these are the two I'm looking at:

One is the high range (0.00-20.00ppt) and one is low range (0 to 2000)

I think the low range one seems more on point with readings I've seen on here but I wanna be 100% sure. Which one should I get?

Thanks in advance!

neither that is way expensive. just get two separate meters. this is all that you would need and you will save a lot of $

Not worried about $$. Tired of using solution to test and re-test multiple res's daily. Convenience is what I'm after and I don't want multiple meters. I've got some credit with dude due to a poor meter I got earlier so they're actually considerably less than that listed price. So I'm going to buy one of those meters I just want to make sure I get the one with the appropriate range.

Thanks!

Ok going with the low range one.... going once..... going twice..... anyone?

I have used both .. they are both great, just a sort of personal preference. Where do you try to keep your ppm's at? If below 2000 the first one (low range) if you never go that high than it is fine. If you need the wide range and/or don't have a problem converting on the fly i.e. 1 part per thousand = 1000 part per million, then the 2nd meter in cool. Just remember that the high range meter has a resolution of .01ppt which is 10ppm. So in other words 1 ppm = 0.001 ppt; therefore .01 ppt = 10ppm. If you are way above this than disregard.

I hope this helps, I know people really pick and choose who to help here.. I am an old O.G. reffugie and man i swear if that forum was still up you would have you answer in 5 minutes! I'am from CO too, U from north or south CO? you can pm me that, i would love to have someone local to exchange notes with. And yes I am legal.

low range... i own one and love it. I don't really see you goin over 2000 ppm anyways for marijuana

Excellent. I'm gonna go ahead and order it!
