pH meters?

[GanjaRobPDX]

I have spent way too much money on pH meters.

Digital meters were my first experience.
I started off with a digital meter from Hanna. I then bought a constant monitor system from Hanna for my hydro set-up. It was then that I realized that neither meter matched up...at all.

So began an experiment to find the most accurate meter around.

I bought several meters: a couple of Hanna digital meters, some off brand dip stick digitals, a trungeon meter, and a milwalkie meter. even in calibration not one of these meters gave the same reading. I calibrated each meter according to its individual instructions and the results were less than great.

I returned all the meters from my experiment and was planning to pool my money to buy a lab grade pH meter...literally a lap-top PC with a probe for testing. cool right? not for $2000 it isnt.

before i made the huge mistake of buying a digital meter for that much money, a buddy of mine suggested I try a Myron meter.

I looked into the myron meter and found it isnt digital, its an analog meter. One big upside is that the myron meter required no expensive probe replacement every 6 months as digital meters do.
The true test was buying two myron meters and getting them to give me the same reading. Safe to say it passed the test with flying colors.
I havent purchased another pH meter since. I just calibrate it every 3-4 months and its good to go.

The price was $400 for the myron meter, but since I dont have to replace probes I am saving money in the long run. I have used these meters since 2004 with only good things to say.
Thought this info would be useful to those who are looking to upgrade pH meters or plan to invest in one.

From my experience with Hanna meters I have to say they are not worth trusting your grow to.

my meter as pictured is the Myron L T-6 pH/TDS combo meter. So it does TDS/PPM as well.

Cool post :thumbsup:....

I use a cheap Hanna pH meter.... And never even thought about other pH pens giving a different reading.... But I've gotten to the point where I can guess what my pH will read and be right just about every time....but that's just me....

I just bought those cheap type from ebay. They are a 3 in 1 meter: light, moisture and PH. I also picked up some litmus paper strips. If I see anything irregular I have a quick check. But the nutes I use are 100% organic and cannot burn the plants at all. Bat guano, worm castings, seaweed and tomato concentrate, seaweed soil conditioner and a rich mix of soil with perlite.

I don't really have to worry about burning at all, I don't even have to flush before harvest.

You can check out my grow journal in the link. I documented it every week and I mentioned everything I used on the plants.

Maybe you might never need a meter again :) LED Logger (http://ledlogger.wordpress.com/)

Good looking unit! I actually preffer meters, to displays. I too had gone through a few, I currently use a hanna, but to be honest I rarly adjust my ph any more. Where i live now at 600 ppm my ph is 5.8, using zeta grow and bloom. I Never would have known of coarse without one, so thanx for the tip. ill check out the myron site

Zeta is the tits! that stuff is amazing and really cheap. Perfect for coco and hydro gardens. No heavy metals...
I use the same shit.

Cool! its weird eh that so few sing its praise. I do wonder if it could use more magnesium, But i just switched from hard to soft city water, it is a plant specific formula at a great price, I used to work at a unnamed store, and i felt good about recomending it.
