AC Infinity pH Meter Kit, High Precision Digital pH Pen with ±0.1 pH Accuracy, Nutrient Test pH Meter for Water Hydroponics Plants, Gardening, Aquariums, Swimming Pools

Finally upgraded my PH meter game to Pro level, the calibration is pretty straightforward, great quality pen, easy solutions to use the pen directly recognizes the USA standard solutions, so if you use NIST solutions you must purchase those separately, the value you get for your money long term by just investing in a powerful stick alone makes it worth, easy settings to configure and navigate.

Been using this meter for about 1 year now and one of the best all in 1 meters. Really helped to dial in my grows. Insures my EC, PH, salts, and ppms are all at the desired readings.

So long blue labs... been using this for a while now. Bought 2 blu lab pens, both showed up dry and failed to calibrate after proper hydration. This pen is tough, reliable, and stays accurately calibrated even when its close to the q4 month QC's. Hopefully i don't need to buy another soon, but i may when the time comes. Easy calibration and the blue backlight is Hella bright!

good product works well fair price

Wish I would’ve spent a lil extra money n got the one where you can test the PPMs and the pH at the same time but you can only get that one on the AC site.

So I purchased the ac infinity pro ph meter kit and when I received the package I was completely stocked and couldn't wait to start using my new meter which was a huge upgrade from my cheap 10 dollar meter. Ok so fastworard a bit...... I get to opening up the package to find a really nice looking ac infinity package staring up at me through the top of the ugly plain amazon box with a nice dark black background and a huge photo of the meter on the front of it so you automatically know what's inside. I pull it up out of the box and could instantly feel the weight of the products and case. I tear off the outside cardboard sleeve and in front of me is an awesome storage case with the company name on top and 2 cheap little clasp to hold it shut but other then that the case is really a nice touch and really helps keep everything neat and in place. So I open up the case and there is my instruction book, my buffer mixes, some cool little containers for each of the buffer liquids when you are calibrating your meter, and a small bottle of storage solution for storing your meter and of course the meter itself. Everything was nice and organized and looked really good sitting there waiting to be used. I quickly got to reading the instruction booklet to get familiar with my new meter and once I felt comfortable enough to calibrate my meter I did just that. I started like the booklet said by soaking the probe in the storage solution for around 30 minutes. I then rinsed the probe in some distilled water and got out my buffer solutions and their little containers. I filled each container up around half full of each solution which is very easy and everything is already marked for you so there is no guessing or anything I then started in the 7 then the 4 and finally the 10 each time getting right on the money and getting my little smiley face confirmation on all 3 solutions. So my ac infinity ph meter is 3 point calibrated and ready to go so I go ahead and get my mixture mixed up and pull out my newly calibrated meter and gave it a test drive. The first time using the meter i got the readings I was looking for very quickly and very easily but....... there is always a but. The second, third and the fourth time using it something wasn't right. I kept the probe in the storage solution and only used distilled water for rinsing so I'm not sure what the issue is but anyways I just couldn't get a good reading. It would just keep bouncing around and would just keep dropping. I mixed my plant nutrients like always and already know around where it should be after mixing but the meter would drop slowly to where it should be but then it just keeps dropping and the smiley face shoes up but quickly goes away because it start dropping some the the smiley will come back for a second or 2 and then it drops more then the smiley comes back then it disappears and the numbers drop some more. I can never get a good reading. I ended up calibrating the meter again and it worked for 1 time great again then started acting stupid again. I calibrated it again and the same thing it worked good and fast again. So I guess if you want a fast accurate reading you have to calibrate it every single use even thought I use it almost daily but definitely every other day and I keep it in the storage solution so it isn't drying out or anything I don't know I am pretty upset with this purchase. I think they should give you more storage solution too because mine is almost gone already but it says to store it in the solution so that's what I've done. It seems really well made and really heavy duty and reliable but for some reason it's looks was deceiving for sure. I do believe the temp on the meter is pretty accurate but the ph number isn't unless you calibrate it before every use. If I have to calibrate this thing everytime I want to use it I think you should send me a lot more buffering solution. I think for the cost it is great the only complaint is that it doesn't stay calibrated and that is a big big bummer. I know you have to recalibrate it every once in awhile but everytime is ridiculous I think. I wish I would have picked a different one now which stinks because I actually did think I found a really awesome meter that I would be really happy with and instead I got stuck with a dud.

Decent ph meter: have to regularly calibrate but seems to be working pretty good. Easy to use and calibrate and comes with a hard shell case to store it in. Middle of the road price range in between the best ph meters and the cheapest. Price was decent for the quality of the product.

My original probe hasn't failed yet but I wouldn't be caught dead without a replacement! The instillation instructions are clean and clear. Install should be simple.

Le doy 4 estrellas por que el medidor no calibraba y lo tuve que devolver,una pena por que confío en esta empresa y lo compro todo,no espere a descambiar por que me hacia falta hacer mediciones y tuve que optar por un producto con un envio mas rapido.

Love it . Instant read is a bonus over the cheaper ones . Highly recommend

Ich habe nichts zu beanstanden kommt in einem schönen koffer wo alles sehr aufgeräumt drinn ist die sonde kann man tauschen falls mal kaputt wirklich ein super gerät

Man könnte meinen die Entwickler bei AC-Infinity sind in ihre Produkte regelrecht vernarrt, ich bin jedes mal wieder begeistert. Die ausgereifte Qualität, das durchdachte Gesamtpaket, perfekt verpackt mit allem erdenklichen Benötigten versehen machen die Produkte von AC-Infinity einfach nur mega Spaß! Das Gerät macht insgesamt einen wertigen Eindruck und man benutzt und pflegt es einfach gerne. An dieser Stelle hatte ich vorher jahrelang einen Combo von Hanna aber hier lässt sich die Sonde ohne teures Werkzeug wechseln, der Koffer beinhaltet alles was man zum Betrieb, der Lagerung und der Kalibration des Gerätes benötigt und nimmt wenig Platz weg. Top!

Ordering from Amazon is always quick and easy. The item arrived on time, exactly as described, and well-packaged. Customer service is reliable, and I appreciate the wide selection and competitive prices. Highly recommend!
