Man. I even got the cool fancy vivosun ph meter for like 30 or 40 instead of 10 bucks and that fucker is reading way off from my brand new ten dollar one. I thought my vivosun one was acting weird. So tired of bad PH meters man. I’ve purchased more PH meters than any other of the same grow piece.

any deals for a fuckin good one @Marq1340 thanks

I calibrate mine in distilled water with 6.86 powder every other use. Ever sense i started doing that I havnt had problems. Could help you. Or you already do this and it's still a shit product as that happens often. Either way. Wacky meters can ruin everything

Are you using ph probe storage solution between measurements?

No. Nor have I tried to calibrate. Maybe I should do so….

The powder solution is dirt cheap on Amazon. I keep a small container with lid of 1 mixed solution right next to the nutes and ph pen. I change it once a month to be safe. When I do change it the difference is only 0.10-0.20 at most. So pretty good I'd say

My recent DOA cheappo one lasted for about 6 months then the last time I went to calibrate it (I was doing that every week and storing in water, not the 'special' storage fluid), It wouldn't grab the 6.86 solution and was only calibrating it to 9pH. It would calibrate to 4.0 but the others were useless.

I took that as a sign from god to get a Bluelab pen...which I think is probably worth it but you have to factor in the storage fluid, a set of calibration fluids, etc.

The cheapest I've seen the Bluelab meter is ~63$ but of course, factor in the additional 30$ worth of bottles...

EVERY PH SENSOR NEEDS PH STORAGE SOLUTION!!!

If you are buying an expensive pen and not buying the cheap storage solution, then you are throwing money away. I use a cheap pen, but I also use storage solution. My cheap pens last a long time, and I can buy a few of them to check against each other is there's any question.

If you are real cheap, you can just make your own storage solution: https://www.rollitup.org/t/make-your-own-ph-probe-storage-solution.999889/
