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

I wanted to check the accuracy of the pH sensor our pool had. I also hate using those tester strips which require identifying if the colour is light yellow or pale amber... I mean, really? Plus those strips are calibrated for a specific temperature, so any result you get with them will likely be wrong if your water temp is outside the norm. Anyhow, I hunted around and this seemed to be the one a lot of people recommended. It came in a neat little kit that included everything you needed in a hard shell case - although I'd recommend also buying some extra storage solution as the included amount will not last long.Use is super easy, and it automatically adjusts for temperature. You can also modify the settings so the backlight changes colour if the reading is outside the ideal numbers. I wondered why the case had an empty spot, then I realised that was so you could stand the tester up with the cap filled with storage solution. A really nice touch. If you want to keep it in the case with the lid closed, you just need to remember to store it on the side so there is less chance of leakage from the cap. Keep in mind that if you store it in tap, pool, or distilled water that could damage and permanently impact the accuracy of the tester. They do say that if it is stored dry, then that will also impact the accuracy of the sensor, but this can be fixed by soaking it in storage solution for a few days. Personally, I'd just get the storage solution - it's not expensive, the cap only requires a small amount, and you don't have to replace it after every use so a bottle will last a while.As for accuracy - I don't have a lab quality reference device to test it against, but it definitely appears to be more than accurate enough at least for testing a pool at home. I can't say anything about longevity as I've only had it now for a few weeks, but the sensor is replaceable plus it appears to be well made - so I think it should last well if treated with the care something like this deserves.They do have a newer version of this that has bluetooth and a "new improved sensor". For me this is more than good enough I think, I don't really have any need to track the readings over time, and as much as I am a geek the additional cost didn't really seem to justify it.Overall, very happy with this tester.

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.

My first ph meter for testing dairy - using it to test super priobiotic yogurts. Was torn between this brand and another well known brand, but went with this one because of the kit, the cap with an O ring and small sponge in the tip that provides wet storage and protection of the probe even when it is on its side. Preventing the probe from drying out seems to be the key to a longer probe life. The Apera storage cap system makes this easy to do. The kit also comes with laminated instructions which are handy. I had been struggling with the paper test strips…never could get a precise reading. Love that this has a 2 decimal point read. I was nervous about the calibration process, but it turned out to be very easy. I’ve used it several times so far and love it. I draw my solution out with a sterile pipette and place it in a small shot glass…insert probe of the meter and very quickly have an accurate reading. Their support/customer service is great too. I called to get some spare sponges for the storage cap (comes with 2 extra), but they don’t sell them. They advised using a piece of any sponge…I found that a piece of small sponge hair roller works well. I would definitely recommend this meter. Hopefully it will hold up well over time.

Needed to PH water tester and after lots of research opted for the Apera PH60. Research easily indicated that going with one of the cheap ($10-$15) testers would lead to inaccurate and frustrating results over time so I decided to spend more and get a quality tester. When I purchased this kit, the price was a good value for all that was included and a strong factor in the decision. It has since jumped up by 25% so I got lucky with good timing. Still, the testing probe is well made, readable numbers with backlight and results have been accurate. I did a calibration upon arrival and it was pretty much right on form the start. The kit includes small bottles of 3 calibration solutions and buffering solution for storage. The case is a nice addition and keeps everything together. Instructions were clear and included on the laminated card in the kit. Make sure to use the buffering solution (good idea to get some extra) to keep the probe tip hydrated and accurate during storage. I chose this model due to it's accuracy, longer life when cared for properly and the complete kit.
