Don't blindly take that list, shop around, deal hunt, and do the research! There are many hidden costs associated with growing ><
I use this: http://www.amazon.com/HM-Digital-PH-200-Waterproof-Temperature/dp/B00132G102/ref=sr_1_2?ie=UTF8&amp;qid=1418095989&amp;sr=8-2&amp;keywords=HM+Digital+PH
Replace the probe every third grow. Calibrate it before use every single time. Period. I don't ever leave it and trust it is calibrated. I also store it in proper solution (storage solution ,or if I am out in PH 4 solution).
Never had a problem, ever.
I am about to go No-till Organics though. Can't wait to not have to deal with Nutrients, PPM, PH etc...
That's over $136 here :( http://www.amazon.ca/gp/aw/d/B00132G102/ref=mp_s_a_1_13?qid=1453661143&amp;sr=8-13&amp;pi=AC_SX236_SY340_FMwebp_QL65&amp;keywords=ph+meter
They work great, and I'd really suggest getting one for hydroponic grows. I use an HM Digital pH-200 which is nice because it comes with a replaceable electrode, so when it wears out or breaks don't have to replace the entire meter. You also will need some pH 7.0 calibration/electrode storage solution as the meter will drift, so calibrate weekly. This meter is on the expensive side of pH meters for hydroponics, but I believe in the "buy it right, buy it once" mantra. Sure you can buy a meter for $40 but you'll end up buying it twice after the first one breaks/malfunctions/whatever, so just get the nicer one and be done with it.
I have tried a half dozen or so, we like the HM Digital one. Use it 4-5x daily going back several years.
