Recommended ph meters

I have a blue lab ph meter and I really liked it. I stopped using it for a while, stored it like I normally would wet bulb. Now it reads around 1 ph higher then it use to. Ordered new calibration solution to see if maybe I have contaminated my current solution.

Was wondering what anyone with some time in with there current ph meter to share a review. Any and all would be appreciated.

Once I try to calibrate my meter I will know if I need a replacement or not. But so far this thing has done me very well. I own a few blue lab items and all of them work like they should consistently. I once had an issue with my ph meter and called bluelab, they helped me repair it over the phone. Cudos to that


Have a wonderful day

I have always used bluelab Oakton and bought a cheap $30 off of eBay, can't post pics but it looks very similar to an oakton and has performed flawlessly for more than a year and I drive it like I stole it. Never clean and let it dry out lots, yes I calibrate (auto) once a week but that's fine .

I've had hanna and Milwuakee and oakton in the past but I always end up letting them sit for too long without refreshing the storage solution and they are toast.

So recently I bought a cheap ppm meter and ec pen from ebay for like $10 free shipping. I've had it for several months and it stays calibrated quite well. I've only had to adjust by .1 plus or minus. Just buy the 7.0 and 4.0 test solutions so you can calibrate when needed.

I use Oakton

Blue lab guardian hands down amazing. Been growing for 12 years now and still kicking myself for not getting something like this sooner. Everything is always dialed in and takes me a quick glance to see what my temp, ph, and nutrient strength is. A bit pricey but worth every penny. I never understood people who spend $1000 in grow equipment, but spend $30 on a unreliable ph meter...water parameters are everything

You Should really think about the PH perfect nutrients. Sensi Grow has done better or as well as any other. #BlueLab

I use a Future Harvest Nutradip pH meter. Works just great been using it for years and just as accurate as the day I bought it !

If you haven't done so already a sulfer burner is a good investment too.

I use the cheap chinese yellow one. Calibrate maybe once a month but its barely ever off. I'm going at least a year straight on my current one.
