Description

Apera Instruments PH60 Pocket pH Tester is designed for reliable and easy pH measurement for general water solutions, such as in hydroponics, horticulture, aquaculture, pools& spas, water treatment, cooling towers, environmental monitoring, beverage making, education, etc. The meter comes with a replaceable pH probe (PH60-E) for general water solutions pH test. The meter is also compatible with 3 other types of pH electrodes and an ORP probe (sold separately) for different applications such as solid samples and surface tests. NOTE: Add a few drops of 3M KCL liquid (included in the kit) to their test sample (usually low ion-strength liquid like distilled water or RO water), which will significantly help accelerate the stabilization without affecting the pH reading.

    • It works, and works well.
Style: Regular Glass Bulb Sensor
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. ... show more

    • Good PH Testing Kit
Style: Regular Glass Bulb Sensor
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. ... show more

    • Works great
Style: Regular Glass Bulb Sensor
The pen comes in a nice carrying case with ph and storage solutions. It keeps its adjustment well and looks and feels well built. Easy to read screen. I have purchased the other smaller ph pen from them and was used to its size but now am used to this larger pen. I’ve needed to contact customer service in the past and they were very responsive. Make sure to read the instructions because you must calibrate the pen in a certain order of ph. ... show more

    • Easy to use, well made, comes with all you need but a bit slow and doesnt seem to hold calibration
Style: Regular Glass Bulb Sensor
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. ... show more

    • Great pH meter for beer/wine making.
Style: Regular Glass Bulb Sensor
Got this for my brewing and winemaking and it's great. A little confusing to calibrate at first but once you figure it out it's not bad. Gives nice accurate, consistent results. Nice carrying case with everything you need.
