Need suggestions on PH meter

Last year I bought a PH meter that was too cheap, and it really cost me in the end. So, before I start this season, I need to buy a new one, and looked through the threads, but couldn't find anything, so here I am.

Any advice on a good PH meter?

Thanks!

I see alot of people using bluelab. (think thats the name) how did it fail you, not precise enough? Or was it not calibrated right? Just curious.

Nurse hatty test strips... more incremental than most... cheap and no calibration to have to screw with...

I dont constantly ph check anymore, got things real happy and just spot check now n again...

I've been using the cheap Amazon ones for a while. I was looking at the Milwaukee 102. It looks nice. Everyone just gets the $150 bluelab combo
I had a Hanna stick from the hydro shop once. It was fine too but needed calibration often. Like weekly. Imo if your gonna go cheap just remember that. And if something doesn't look quite right to double check with drops.

Hey pal, maybe you could save money and just use the liquid shaker with the dropper bottle.

It's close enough for the plants were growing. I actually sold my meter because it's just more hassle. The liquid dropper Its super fast and you know for sure that it's calibrated every time

that all I have ever used....maybe not as accurate as a meter but it doesn't hurt (in most cases) to have a slight variation

Quite cheap if you buy the re-fill bottle

Thanks everyone. I'll look into the bluelab, and just may go with the drops afterall ;).
@GeneBanker, it failed by not sensing well. It had a sensor for moisture, and even just after I watered the plants, it would read "DRY".....ugh. And, the PH would read too low. I messed up also, and over fertilized it, meaning it wasn't just the meter :roll:. I had been reading threads on using PH, and misunderstood. SO, between the meter and my little pea brain, I had yellow leaves dropping everywhere. I've got to get it better this year. My yield wasn't as good as it should have been.

I have a Bluelab. It's a good meter. Highly recommend it. Costs more than others but the build quality is worth it.

With the bromothymol drops/color chart...how do you all get an accurate sample reading if you use black as coffee additives like humics and kelps and whatnot with the base nutrient fertilizer solution?

Oh you have a three way soil meter. You want a ph pen. I use a jellas brand meter. I think if I where to use one again id get the blue labs. The good old drops are the best though imo.

If your doing soil and not hydro or soilless. I wouldn’t even worry about the ph. Especially if it’s decent soil it should buffer just fine. The only time my ph meter is being used is in the hydro room. So I would t waste the money on meters or anything. Now granted I’m assuming your water isnt coming out of the tap at a ph of 3 or super high like 10.

@Susanne Whatever brand of pH pen you decide to use. Its Important that you also pick up a solution of 4.01 and 7.0 pH reference solution to calibrate it and to keep it calibrated. Rinse the tip after each use and store the node in either RO water or the 7.0 reference solution. It's a sure fire way to keep your pH meter accurate it's entire life.
THIS^^^^ Follow this and you should get maximum life and accurate sample readings from whatever pH meter or pen you get.

Also...its what Ive been doing for years...is to get a cheapy 20 dollar yellow pen or the color drops for backup. Whenever you suspect something is off or just not the norm with your regular go to meter..you can back it up and/or get confirmation of whatever your trying to do with pH.

Exactly what I do. Except now I'm itching to upgrade to cmh and now I figure well I could just spend.way too much and get the gaurdian and a new chiller

If your recirculating your nutrient solution in a nice reservoir..the Blue Lab Guardian is probably the best in its class. That thing is pricey but worth every frikin dime. Total tank and crop insurance. You cant grow wrong with the Guardian.

I am new, but through my research I have heard good things about the Apera PH20 pen. Its around $50 and I'm told it works great.
