pH Meter - What to buy

[Californiakid]

I need to clean mine today. I had to calibrate last night and again this morning. I fear the day cleaning doesn't work anymore. But that will be down the road a ways I'm sure.

Yep ,that toothbrush has saved the day a few times for me too.

I use the Apera Instruments meter. Highly recommend it. Amazon link http://a.co/5GIi84T

Hey Grinder, I heard those Apera, models, were good ones, good company, don't know ,just heard that.

You should be able to soak it in storage solution to fix it when it dries out. That another reason I like the Hanna, replacement parts. Quality isn't cheap, cheap isn't quality, something I've learned through the years with tools.

> Yes, you can keep them in water too, all you need to do is keep it in a cup with water.
Actually, storing the probe in water is bad for it and will shorten its life. Storage or calibration solution helps to maintain the ion gradient across the probe tip. There is some subtle chemistry and physics going on there, so anything you can do to help maintain the glass electrode is all for the good.

You want to clean the delicate glass electrode very gently. A toothbrush is too much!

> The meter comes with powders, but if I can simply store in the calibration fluid I wouldn't mind doing that route. But it begs the question of what role in the market storage solution plays. I mix water (and thus will be using this) daily during grows. I will then store for a couple months this summer. I think the calibration fluid would be fine for daily, so am leaning that way.

Unless you have analytical glassware lying around your kitchen for precise measurements, it's hard to mix those powders to the level of a calibration standard. Better is to buy it.

> The best option there seems to be the kit with both 7.0 and 4.01. Could they both be used as storage?
Storage solution is best.
4.01 is next.
7 after that.
Don't use pure water.

Thank you DoctorJohnson I got both calibration fluids, so will plan to use 4.01 as storage.

 

[Campesino]

Thanks to all for your input and advice!
I got the cheap meter, Vantakool, but also invested in the calibration fluids. I think that if I find using a meter to be far superior I will eventually upgrade, but I am not yet convinced and it seems that $12 is not much of a risk.

Another case of your ful of it.how do you know what kind of toothbrush I use??
Are you that smart, hahaha

 

[D.A.A.S.69]

Been keeping them in water for years ,no problems. So wrong again

 

[D.A.A.S.69]

Supergenius, in his own mind. Nobody elses ,Not to worried ,if it hurts my 15buck meter. I use water.

 

[D.A.A.S.69]

Well good, I bet it works just fine.

 

[RosettaStoned]

Haha I sense some animosity

 

[D.A.A.S.69]

Yeah, but Bluelabs are the sure enough good ones.

That was a rude thing to say, DAAS.

Here's the link again if you'd care to learn rather than just make insults. tps://hannainst.com/ph-electrode-m...ibration-guide

 

[D.A.A.S.69]

All of your remarks, are rude, you act like your ways all ways right, an everyone else is wrong.
I've used a toothbrush dozens of times over the years on cheap ph meters, never hurt the first one.
You need to think a little ,before you put down everyone elses. Matter of fact I will never read your posts again.haha ,lol

I'm for BlueLab all the way.. Accurate, easy, reliable and saves on a lot of stress .
Good luck to you in your growing😊

 

[OzBud]

Actually, Blue Lab themselves recommend using a soft toothbrush to remove heavy contamination from their pH pens
