Hiya,
So litmus paper/liquid ph testing solution just won't cut it for me anymore. I'm looking for recommendations on a meter, hopefully from peeps with personal experience. I have seen most of the models of the big brand meters, milwaukee, hanna, oakton, etc. But I still feel kinda confused on some features, and I also have extremely limited experience with this piece of equipment.
Some criteria:
-budget is 100 bucks (hopefully including first purchase of buffer)
-to keep cost down i'd like to stick with single point calibration (will be storing in this buffer)
-easily/cheaply replaceable probes
-tds/ec readout as well as ph
-accuracy to +/-0.1 ph point is fine for me
-no preference for temp adjustment but I do think I would prefer manual calibration.
I don't really care about pen vs stylus style (obviously benchtop is out of my range).
My biggest conflict here comes from something I saw someone post elsewhere: pretty much all ph meters that are not top notch require constant calibration and so why spend 100 bucks on a meter that has the same accuracy and lack of stability as the lower end models, say the 50$ hanna pens. Is there a meter out there that, without breaking the bank, is really going to be worth the extra cost?
Also, do ph calibration solutions have known tds/ec values or will I have to buy separate solution to do that calibration?
