ph tester needed

Could you name a manufacturer who recommends distilled water? No one recommends what you're suggesting.... KCl is what you want that's what's IN the probe, and pH 4 reference solution will work...at $10 a liter, it's way cheaper than a new probe....those "High end" manufacturers supply equipment to real scientists, not just hobby gardeners, so it pays to learn from them.
 
Agreed. You should not be soaking in DI or distilled. Just for rinsing off solution films over the sensor after testing.
But not all probes are the same. Some have the fluid (no soaking required) and others do not (dry bulb = dead meter). I have seen $3000 professional meters turn into paper weights because some moron let the bulb go dry. This was at a hydro power plant and had nothing to do with gardening. More for corrosion effect on metal.

HappyDaze It seems you are determined to be right. I stumbled upon this solution myself, but later picked up this manual with a $14.95 pH pen. See attached photos. As you can well see the manual says soak in distilled. Since you are a self acclaimed scientist where is the "science" I requested?

It even worked on this higher end pH/TDS meter which didn't cost and arm and a leg. You do realize that scientists have unlimited expense accounts?

This meter is kind of nice, because you can change out the probe as it has a coaxial cable connector. That is the usual failure the electrode. This is the pH/TDS-2983 Multi parameter continuous measuring instrument. (Damn sounds "scientific"!) I don't like getting into flame wars....Go do a bowl!

Flame war?? haha...do what you want with your dollar store gear. Advising others to follow along? meh, not so helpful to the community.

Just sayin...
 
Whatever you think "value" is...go for it....like I said above...the CANADIAN MADE NutriDip meter I recommended, lasted 15 years....I never needed to "think about it" sport, it worked every time I picked it up (probably cuz I knew how to look after it). :) BTW....didn't the O.P. ask why his/her meters were crapping out and for RECOMMENDATIONS?

Talk about jacking a thread and telling people what they should do?...LOL, your hatred of all things Chinese is duly noted, gotta blame someone for the state the States are in, eh? How's that wall coming along?

Nuffsed?
 
No still not "nuff said". You asked for me to furnish the name of one manufacturer, and I provided actual photos of their manual. In a debate one should provide factual documentation, and you have not. I asked you to provide the science behind your assertion. I know quite well what the the higher end manufacturers state in this regard, but could there be a financial incentive? Still waiting for the science behind your claims. I have deleted some of my negative commentary which is not apropos to the subject.
 
HappyDaze is correct. You never want to store a meter in RO, DI, or distilled water. That’s one way to shorten the lifespan of a meter.
I can’t see what the other guy staramus is saying, because I blocked this guy a long time ago.
You can add individuals to your ignore list. I suggest blocking out any and all consistent spreaders of misinformation on this site.
 
I may have come across as dissing anyone who buys inexpensive gear, and that was definitely not what I was saying. There's two schools of thought when you're spending your money. You think, "hey this is great deal, it'll get me started", or "I'm laying down the cash for the long haul". This applies equipment and seeds too for that matter. (Am I going to lay down US$350 for a fresh pack of some Mendo X and grow it once, no).

If you look after your $40 Hanna dip stick and it suits your needs, great. I threw down for a multi meter and spent way more, hoping it would last (and counting on the 5 year warranty if the thing shits out).

Everyone's situation is different, and circumstances change. A year and a half ago, I blew CAN$1500 on a new LED and a bunch of stuff I didn't really need, and now I'm mixing my nutes from a pack of $22 powder to save a little $$$.

Peace

EDIT

Toker1 this is hilarious... I think the guy blocked me.

I didn't say store I said soak, and it worked. Toker1 blocked me because he was attempting to be the authority on a subject he had no experience in. Namely ordering from Seedsman, and their customs problems. No loss to me, I do not go along with unquestioning authoritarianism.

HappyDaze you should back off on many of your assumptions such as my politics. You could easily have furnished the simple description of what occurs when "STORING" a pH pen in distilled or deionized water as is found here at this chemistry forum. https://www.chemicalforums.com/index.php?topic=50263.0 I soaked, and it removed whatever residue was on the glass electrode.

Many years ago when using what are the yellow now $10.00 pH pens (I think I paid $7.00 then) I asked this same question https://www.rollitup.org/t/using-distilled-water-to-calibrate-ph-and-ppm-meter.229779/ This led me to the method of soaking the pens when readings became erratic. My pens are working fine, and reading right on. I asked my plants, and they are loving their pHd water, and nutrients.
 
Apparently all he can do is parrot a manufacturer. I don't see how he has any time to grow as he spends all of his time on this forum. Maybe his growing is only theoretical.

i have bought 2 electronic ph testers that dont seem to work, can anyone reccomend a ph tester that they use
Click to expand...

rcsaw If you would supply some more information maybe "someone" could come up with a solution to your problem. Isn't that what this thread is about? I did PM you.
 
I use the droplets as a PH tester, I used for years at a job I had in the past. So the usage was second nature to me. It is also inexpensive and reliable, every time!
