Whats up growers can some one recommend me the best ph meeter I got these 2 they the same but both give me different readings 20231127_062943.jpg
 
I’ve had luck most recently with the Apera ph 20. After going down a rabbit hole of research about different probes, the Apera uses a type of probe that won’t completely die from drying out. It can be “reconditioned” by soaking it in the storage solution and recalibrating it. The probe itself is also replaceable, so you don’t have to trash the whole meter if it does die. It’s half the price of a Blue Lab pen, and comes with a nice storage case as well as calibration/storage solution.

I don't understand how you can keep those ph meters probes wet. Mine have to be stored in kcl storage solution, when not in use.

I use the cap that comes with the probe. Like in the picture the one on the left isn't capped completely. Could be the reason for two different readings. Attention to detail, could be the difference between an okay grow and a good grow. Or I am too stoned to have a reasonable opinion.

Unfortunately, junk and junk.
Unless you're willing to spend $50 on an Apera PH20, you'd be better served with the GH pH drops.
Those ubiquitous $15 pH meters are borderline useless.

Agree. These kind of pH meters are great to get you off the ground for your first grow, but if you're going to continue, it's worth investing in an Apera, or Bluelab, or similar mid-grade consumer level meter as well as the storage solution & calibration solutions. I have a Bluelab right now that's been solid, but might opt for a decent Apera with replaceable probes in the future. My only other thought is to pick one that meters quickly, since it can be a bummer to wait 5 minutes to get a meter to settle in.

I hadn't heard that before, can you post a link?

I can recommend the Apera ph-60 and Milwaukee mw102, both are quality meters.

You never answered whether you have tried calibrating those two meters... I've used a few of the "cheaper" meters and some work better than others, even two new identical meters - even after calibrating... The cheapo I'm using now is remaining accurate and I keep calibration solution in jars for checking/calibrating...

Just received a "better" multi-meter (pH/PPM/EC) that I will be returning as it seems to have a cold solder joint on the circuit board that is keeping TDS/EC functions from working properly... When switching mode from pH to PPM it may or may not flash a reading for a split second before reverting to zero and only once displayed an EC reading before reverting to zero... Replaced the batteries with new and had the same results...

My advice, always keep new batteries onhand, preferably 357/303 Silver Oxide instead of the cheaper LM44 Alkaline's they come with... The 357/303's last far longer and give steadier readings... Well worth the extra expense...
 
I use the bluelab guardian. I also have 2 Ph probes that are replaceable, and I find, if I switch them out every other week, they stay accurate. I've had both for quite a long time. Cleaning, storing, and calibrating them often, makes them last longer.
 
I feel like it depends on how accurate you need to be. Hydro you want to be accurate as possible, soil you still want accurate, but it's not as crucial, imo.
