      What do you mean by not working? Did you calibrate them?
      4x4 600w HID (empty for the summer)
      3x3 400w HID with 4 skywalker kush (new strain for me)
      2x2 65w Quantum Board LED with 4 mother strains

        I use the same meter as ATU and it is real important to not let it dry out cause its junk then , bring it in to a store and they will test it for you and show you how to calibrate it if you dont know. and it takes longer than 15 seconds for ph to balance out .In fact how long does everyone leave there ph meters in nute mix before taking the reading , I go until it stops changing 20 seconds

          Yes, I test until I reach stability. I swirl around the water with the ph pen and test while mixing the water around. This ensures PH uniformity through out the medium. Then I clean with DI water and store ph probe bulb in a storage solution. Calibrate 1-2 per year.

        Het RC...I had a Nutradip meter that I used for fifteen years, it needed new probes every few years, even though they were well looked after. As everyone will tell you...you can't let them dry out and you should store them in pH 4.0 test solution or storage solution. I'd recommend that brand based on my experience

        My new meter is a BlueLab combo meter. I've had it for about a year and a half, and it's great, but it displays one output at a time. I liked the Nutradip better, it displays all three reading simultaneously, and doesn't run on batteries, which may or may not be an advantage I suppose.

          If you are testing 1-2 buckets, sure. I can see that. Now if you are testing 100 buckets, that would require way too many man-hours to use the strips.

        i have the same that ATU and OJH have but i also have a cheap yellow chinese one and the yellow one its always spot on and needs no calibration, the fancy one needs calibration once a month at least. buy a cheap yellow one i would say

          Agreed, my cheap $10 no name brand yellow PH pen has lasted me about 5 years now. I went a year with no calibration at all and the pen was only .1 off the calibration solution rating.

        You might try soaking them in distilled water for about an hour. I resurrected one of mine with this procedure. Give it a shot you've got nothing to lose.

          I think soaking in pH 4 calibration solution or KCl would be better. Based on what I've read, keeping a probe in RO or distilled is what screws them up. Oakton, BlueLab, Hanna....all of them say the same thing.

        #10
        Some manufacturers recommend soaking in distilled water. I did purchase MA 9015 pH electrode storage solution, but I prefer neutrality. This method has worked on two different manufacturer’s pens. The results have proven satisfactory for me.

          Could it be that the “high end” manufacturers just might want to sell you expensive solutions? I would need to see the science to change my mind.

          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? Click image for larger version

          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!

            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 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.

            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 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.
