What Ph meter is everyone using, and what do you think of it?

[F_Dupp]

Hey everyone. Im in the market for a new Ph meter and was wondering if anyone has any recommendations. I run a low pressure aero system with 35 gallon reservoirs and am currently using an Oakley Ph pen and it no longer calibrates correctly. What is the best meter you have used?

 

[RonnieB2]

Im lucky. I have very clean and stable well water. I only use ph up ph down with the test kit

I got the cheap shitty yellow one. It works but needs to be calibrated often. I use a liquid color-match tester just to make sure the meter is accuratish and shoot for a pH of 6 so any inaccuracies won't hurt the girls (I'm in DWC). I hear the $80-$100 blue lab one is very reliable though.

i love my blue lab leap meter. My old bluelab pen was nice, but this meter has a replaceable probe and can also be used directly in any media even directly in soil. It also reads much faster!

My buddy swears by that yellow one. And you're correct. Hes calibrating constantly lol

Unfortunately the buffer powder is expensive. Luckily, I've discovered that you can save the solution in a jar for a couple of weeks so that help A LOT.

Apera PH60S is my favorite, it will read soil or coco as well as liquids. The normal PH60 is cheaper and is liquid only. Gets readings fast and has 2 decimal point accuracy.

Bluelab makes a great pen, slower to read, 1 decimal precision.

Milwaukee are great.

Also the pens from HM digital are okay if you are on a budget...

I'm on a budget and after 3 cheapos, feeling like HM digital came through for me regarding consistency. And I think the com-80 tds from them is even better.

I don’t check ph. Lots of nutrients have ph buffers..

Before that...I still didn’t check ph. Tap water is good here.

I used to use a $2 one and it was fine

 

[CrvenaZvezda]

Most of the ones in the 10-20 dollar range are fine. Apera instruments used to sell their cheapest one for like 40-50 and they’re a fairly reputable brand. Im currently running blue labs and am happy with it but feel it is over priced. I guess time will tell, so far I’ve had it for a year with no issues, if I get 4 more I’d considering it worth the price.

hanna groline combo, the one with the external probe. ph/ec/temp, and reads ph down to .01. had it for about 3 years or so now, only had to replace the probe once. its my favorite out of that ones ive owned

Same ol' cheapo I bought in 2013 from Amazon. I check calibration ~monthly, and have never had to adjust it once (that I recall). Registers 4.1 with the 4.0 pH control, and exactly 7.0 on the 7.0 pH control liquid.

Milwaukee are great.

Milwaukee MW802, no adjustments in months. Very happy with it.

What have you been storing yours in?

 

[Gemtree]

Hm PH-80 Checked it twice in the last 6 months and it was still dead on

What have you been storing yours in?

The meter? I used to keep it in its original case, but now I just leave it in a drinking glass along with my PPM meter in the bathroom I use to keep my nutrient tanks in.

Thought some kind of buffer was needed to ensure long life of probe.
