Reddit mentions of Dr.Meter 0.01pH High Accuracy Pocket Size pH Meter with ATC Backlit 0-14 pH Measurement Range

Two questions. First, I bought this pH meter. Reviews seemed generally positive, but I found even having it sit still in calibrating solution for an hour it jumps around SO much which seemed to make it unusable. Is this common? Are there other products that zero in on a pH value better and don't cost a fortune?

Second, I bought this refractometer. Seemed to work very well for OG measurement as compared to my hygrometer. Can someone clarify, can I use this for later SG measurements? Based on discussion, I must use the Brix scale, then convert to SG?

Nice tip, i'll remember it ! Just tried it, i mixed 3tbsp of soil with 3tbsp of tap water in a glass. I filled another glass with just tap water. 20mins after, the glass of tap water is at 6PH and the mix of soil & water is at around 5.75

So if this test is accurate it means my soil PH is under 6 so i should stop feeding them lemon juice right now. Is there something like lemon juice to raise PH or should i just stop messing with PH and feed them water ?

Note that the PH tester i'm using is very cheap and could also be inaccurate : https://www.amazon.ca/gp/product/B00LNSEZH2/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Have you any interest in a ph meter? THey aren't super expensive, and are really useful in your brew kit. I also use mine to test viability of starsan solution, and they could be used to test "sourness" of a lacto ferment. At least you'd know ahead of time if there are fluctuations in your base water, which would explain mash fluctuations.

I use a baking soda solution and acetic acid (vinegar) to calibrate mine on the cheap.

This is the one I have. Good because it reads in .01 resolution. Reads out just fine. Just make sure you purchase 4 and 7 pH calibration solution, as well as storage solution so the electrode doesn't wear out. I'm sure the more expensive ones are tres better, but I don't have that kind of a budget.

Just a note on that soil pH meter- for about $4 more, you can get a pH pen that can be calibrated for accuracy. I have had bad luck with the dual prong, in the soil types like that one, not particularly accurate.

Thanks. Would you consider this a decent pH meter?

If not, any suggestions?

I've had good results from this one: http://www.smile.amazon.com/gp/product/B00LNSEZH2?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00

You'll have to calibrate it before using it and clean it after use, but if you do that then it's spot on
