[JohnyPotHead420]

seen them before very nice for the price for starting out

 

[bigbudahluva]

gotta help new growers surely, i get so many private messages off people with defficiancies off incorrect ph. Any other cheap tips for newbies suggest away

 

[brimck325]

here's where i got all my pots when i first started indoors....ready.......graveyard, week after valentines and easter they throw em away.....

Save your money and buy a real pH meter.

Nice price. I have a similar model that has a problem with the on/off switch. I will probably order a couple next time just in case. Having the proper ph after adding nutes is one of the mistakes that I made on my first grow. Not calibrating the tester was another big mistake - get the 7.0 solution.

 

[bigbudahluva]

7.0 and 4.0 calibrating solution

Anybody trusting these cheap pieces of junk will be back on here singing the blues about it later. Either they crap out or are so inaccurate they lead you to do the stupid.

I can not say...sometimes no name brands do work as well as 'labeled' brands... but I spent the extra 9 dollars and got the Milwaukee one, which is probably one of those with just a stamp on it

I saw a digital ph meter at Lowes for $15, looked a lot more sturdy than those do.

 

[hotrodharley]

For soil - maybe. Hydro? Never. JUNK!!!!!

 

[stillfungi]

This looks like the same thing on Amazon for under $8. http://www.amazon.com/Neewer-Digital-PH-009-Multimeter-Tester/dp/B005DWGR20/ref=sr_1_3?ie=UTF8&qid=1351959637&sr=8-3&keywords=ph+tester+for+water

yeah they work fine for a while think i had one of those for my first one had to calibrate every time i used it tho but it would work if on a budget

Not sure about those ones but I have a cheap analogue meter (meant for soil) that does moisture and pH.
The moisture bit works well enough but the pH is a joke. Only a very vague idea at best.
I like the drop tester kits for hydro. £4 lasts me two years.

The cheapo ph testers are exactly what you pay for.

I have tried the milwaukee and the exact ones shown in the op. I may have well just thrown my money in the street. They kept getting out of calibration and then they stopped working.

I was using a drip tester to calibrate, it was a pain. Now I just use the drip test. if you are not color blind they are very accurate.

Piss yellow (no orange, no green), 5.8

The drip test kits cost about $7.

I spent big money on a ph tester and it crapped out too.

Everything in medicine was analog and then digital for measurements and assays - pH, Conductivity, etc. A nurse still cannot be colorblind when working in many areas as test such as "drip" as trousers call it work every time, no exception. If the test materials are not WAY expired and have been kept sealed and dry they are (almost) foolproof. Depending on who is testing.

BTW by "dry" regarding liquid test solutions - many are hydrophilic, meaning they attract water. A solution that has been "watered" down even by RH is questionable for accuracy. Keep the bottle clean and sealed, in a cool dry place, and it will serve well.

 

[Trousers]

I am sure there are some fine, expensive ph testers that work well.
I just have not experienced success with any digital testers.

Many need to be stored with the contacts in water and calibrated regularly.
Not storing the tester correctly and not taking care of the contacts and calibration could lead to disastrous results.

Yep, that's what I meant Hotrod.
I use the 'Essentials' pH test indicator though. Looks the same. It comes in two forms and I use the 'narrow spectrum' one. It's only meant for 5.8 to 7.4 but i use the same colour charts as you. When i fill the res it drops below bright yellow to a tinge of orange I leave it for a day and it seems to come out about right and hold it there. Unfortunately, my straight tapwater comes out blue. (on the pH test).
One thing to note is that it's hard to tell he colour under an HPS. Better off going outside and comparing it to a white sheet of paper.
Another thing I've noticed is that if you leave the test in the tube over a period of hours/days, it shows up as more and more acid.

Bought one of these cheap ones with the 7.0 solution, NEVER had a preoblem with it, its NEVER gone out of range on me. I grow hydro and its never let me down. My past 2 grows have been pretty much issueless, and I have to give credit to these 2 meters. Neither cost me more than 20 bucks...and they've withstood daily use for the past year. So...I dont consider mine "junk". I'll buy em again if and when these go bad. Screw paying all that money for name brand shit. Foolishness...
