Apera Instruments AI311 Premium Series PH60 Waterproof pH Pocket Tester Kit, Replaceable Probe, ±0.01 pH Accuracy, Lcd displayCarbonfree Certified

I got this PH meter for testing water during a alchemy experiment. The meter came with all you need to get started which was perfect, especially the 4 triple AAA batteries. Just as they said the tip of the meter has droplets of water on it when it arrived to make sure the meter works right.Followed the instructions to the letter and was able to calibrate the device easily. Swirling the meter in the calibration liquids as the instructions say is a must to make sure air bubbles are removed.I like that you can re-use the calibration liquids for set amount of uses. Product feels durable, while also waterproof incase the device falls into your test subject. Testing the water PH in my experiment worked great. Just follow the instructions for proper use and storage, you should be fine. No complaints, the product works like a charm.

I have had my eye on this PH meter for some time now, as the cheap meter that I have been using for my home brewing and charcuterie hobbies is barely up to the task. Finally, the price on the PH60S fell to a point where I could not pass it up. The order arrived promptly, and as I unpacked it, the quality was immediately obvious. The unit comes in a protective case containing the meter, 4.0, 7.0 and 10.0 ph buffer solutions, calibration vials, and additional KCL storage solution. Also included are a lanyard for the probe, a printed user manual, and a laminated quick start guide/reference card. Set-up and calibration were fast and easy thanks to the clear and concise instructions in the user-manual. I was impressed with how quickly the readings stabilized during calibration and my initial testing. I was also pleased with the bright back-lit screen which made it super easy to read. I don't foresee having any issues with this meter, but if I do it will be easy to contact their support team since their phone number and email address are prominently displayed on a sticker inside the case. It is clear that Apera Instuments pays attention to detail. I highly recommend this meter.

We looked carefully for a quality PH Tester resolution reads two decimal places. The Apera PH60-WW has all that we needed and more. It was shipped promptly and most other testers the sellers did not have the PH tester in stock. It came in a quality carry case with the necessary solutions for calibration. We also like that the sensor is water proof. The batteries are included. The manual clearly explains how to calibrate it. We are very happy with this purchase.

I've been quite pleased with this pH meter. It's easy to calibrate and works well. It comes nicely packaged with everything you need to get started. You will want to purchase a bottle of KCl solution as it only comes with a small amount. Really helps me keep closer tabs on the pH of my hot tub, which is often hard to stabilize.

Nicely made and super easy to use, but find that it often can take several minutes to settle on a stable reading. Even when it comes up as stable, it will sometimes start changing again after 10-20 more seconds. Waiting on this probably isnt super important if you are shooting for just a semi-tight range and not a super precise exact value.Also found that every time I go to use it (lets say once a week at this point) when I check it against the calibration solutions, it's a little off and I have to recalibrate it each time. Hoping maybe there is a 'break in' period with the probe or something and that it will eventually hold calibration for longer.The way the tip of the probe section is (the plastic around it) it seems to often trap an air bubble inside it and can be a little tricky to shake the bubble out without just introducing a new bubble inside it.The timer for the backlight is pretty short but you can set it to always on instead in the options, would be nice if you could keep it on a timer but set it to longer so its not constantly turning off on you.The storage cap does not snap on, just press fit around a little gasket. It seems to always want to pop off ever so slightly, so when its laying down in the case sometimes the 3M KCL storage solution will leak out of it. Also seems you need to fill it slightly past the 'fill' line so that when its laying on its side the probe is completely covered. And speaking of the KCL, it comes with the tiniest amount so you'll probably want to pick up some more (which is common thing said in most of these reviews).It comes with a generous amount of the calibration solutions, but with the 3 vials for using during calibration, be careful with the tops. They need quite a decent amount of force (till you hear/feel a hard 'snap') to close otherwise they also will leak out into the case while they are on their sides. Then they are also a bit difficult to get the tops back off, they dont just pop off with ease, you have to force them off and I always feel like I'm going to spill them all over with how much force it takes to open them back up.The case itself is quite nice. The plastic does not feel cheap at all and the latches are nice and secure, except I do wonder if the thin plastic joint where the latches attach to the case will last after a while of them bending back and forth from opening and closing them. Inside the foam seems high quality and solid with the appropriate cutouts for each thing. The instuctions are very well done and simple to understand and follow.Overall this is a massive upgrade from the cheap test strips or testing drops etc. Not having to match up very slight differences in color shades and guessing which is close (especially if you're not testing something that starts off clear, such as a water/nutrient mix). Granted it's also a lot more expensive then those options as well, but the quality of it gives me the impression that it will last for a while (and with the replaceable probe, that should increase the lifespan though I will admit I have not looked at what a new probe would cost).Don't bother with the cheap digital testers that amazon is flooded with, go with quality from the start and you'll be much happier in the long run.
