Someone suggest a good PH meter please

[Guest]

I have had 2 types of Hanna PH meters, the first one was the standard 1 adjustment dial. It lasted about 4 months, cleaning fluis soaked in coton in cap for storage and calibrated every week like they suggest. Couldn't adjust it low enough after 4 months, was about 2.5 PH higher than calibration fluid. I bought the Hanna dual adjustment ( one for 4 clai fluid, and 1 for 7 cali fluid) followed same regiment os storage and calibration technics. It lasted 1 month. And its it like 4 PH higher thn cali fluids. I wanr to get a good replacement, can anyone suggest a good one that has been tried and trued?

Thanks in advance

I have a bluelab truncheon,ec,cf and ppm readings.Very acturate!Expensive but worth it.

enahs, I'm using hydro with hydroton. I take my reading in resivour.
They last me about 4 months tops. I went back to the paper litmus PH testing.

igohydro, you have a link to where you purchased yours?

i used a hannah meter too, bu tit quit after a while, same ting, couldnt adjust it below 7.
the blue lab truncheon does not measure ph does it?

I have the same one as Sleepy... it's a nice unit, had it for almost a year. Very durable and dependable - it's always on point, and I check for calibration once a month.

Before that I had a Hanna that got submerged to deep and shorted out. Lesson learned is you have to have a waterproof unit. Otherwise you can fry the motherboard if you go too deep.

Thanks for posting the question, its one I've been wondering about.

I have seen some recommend the nutradip trimeter. The thing has large easy to read displays for all 3 readings.(ph, tds, and temp I think) Bigtoke uses it.

That link sleep listed has lots of great items.
There is a matching conductivity tester for around $55.
So for about $100 you could have it covered, the nutradip runs around $225.

If your growing soil, the soil test kits are showing up on shelves. Got one for $11, 4 different testers, kinda like checking a swimming pool. Get a jug of distilled water to go with it.
Peace, 2buds
Killing them one day at a time. Hopefully the test kit is sending me in the right direction!

I have the Hanna combo meter and I guess I've been lucky... It's been great for over a year now. I calibrate it every 6 to 8 weeks and it's only off by maybe .2 on ph and 50-75ppm. Hope it stays like that

they do make a ph truncheon, but it only does whole numbers on the ph scale if i remeber right....wouldn't be too accurate.

I use this one after not having one last grow.. Man, its nice to just leave it in a tub of water to see the ph drift up overnight.. Generally .5 in 24hrs.. Nutrient..at least the ones I use tend to drop the ph around .3-.5 FWIW
