Apera Instruments PH60-PW Handheld pH Meter Tester Kit with LabSen 805 ATC pH Electrode for Lab-Grade pH Measurement in Pure Water and Water Solutions with Low Ionic Strength

Bough the pH tester for use in making probiotics fermented fruit juice. The included instructions were detailed & clear and calibrating the device before first use with the included calibration solutions was quick & easy. The device is easy to use and well made. Would highly recommend it anyone who is serious about testing food samples quickly & accurately.

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.

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.

Calibration is important and finicky - but this will be the same for any pH meter (acidity/alkalinity meter). Apera provide solutions and OK instructions to calibrate. But the provided solutions don't go very far - about 10-20 recalibrations and I think they have a use-by date about a year out. My solutions were shipped already out-of-date - Amazon took care of that with a generous refund with which I purchased fresh calibration (buffer) solutions. The provided instructions are poor for the general user but with a bit of interpretation I found I could calibrate and use the instrument accurately. There are more expensive meters but they're really for laboratories and will be just as fussy. There are less expensive meters but I think this is around the best price/value for an accurate gauge of your water supply acidity/alkalinity. You could go with test strips but my experience with these is they are quite inaccurate. I wanted to know why my copper pipes were being corroded and my water was turning my shower curtain blue. I wanted to check water quality. I thought acid water from my well may be the culprit. The problem is once you've sampled and sent to to a testing lab your samples may no longer match what's coming out of your tap. For instance, some acidity may be caused by dissolved CO2 which will off-gas in transit raising the pH. Also a single test lab may cost you about the same as this instrument.

Bon produit, un peu lent a stabiliser. j'ai change pour le PC60, pour a peine plus cher qui fait la conductimetrie egalement.

Estupendo para controlar el PH de mis cosméticos caseros. Excelente calidad.

calidad y presicion

I use a ph meter for plant nutrient solution. Previously, I had a couple of cheap China imports, which seemed reasonably accurate for a while, but don't last long. All ph probes degrade over time, so rather than keep buying cheap, I decided to get a more reliable one with a replaceable probe. This is quite expensive compared to some other brands with good reviews, say the Essentials PH Meter, and @ £29 the replacement probe is not much cheaper than buying a new Essentials meter. However, replacing just the probe reduces waste, and gives you options: there are 4 compatible probe types (all available on Amazon), which you can buy separately as replacements, or to measure different substances. The glass bulb is for liquids, the spear probe for solids, such as foods, soil, the flat probe for paper, cloth, skin etc. And you can buy an ORP (Oxygen Reduction Potential) probe to use with this meter, which tells you the "killing power" of your solution/water (sterilising or not, a simplification of complex subject). The life of the probe will depend on how often you use it, and how you treat it. The probe is supposed to last 12 - 24 months - it's CE rated for 6 months (for safe use), but that's NOT its life expectancy. It CAN be stored dry, without degrading it, according to instructions, but storing it dry will affect its sensitivity. So if you store it dry, for accuracy, you need to soak it in the provided solution before use. It can be stored in the soaking solution, but NOT in purified water. The kit comes with everything you need: soaking solution, 2 calibration solutions, batteries, lanyard (quite a long one), 2 containers for calibration, instruction manuals in English and German, as well as a laminated quick reference chart, all in a hard plastic case. The instructions are clear, easy to understand, and contain all relevant info. Instructions say not to use soaking/storage solutions from other companies, but as long as the same (potassium chloride or kcl @ 3 molar strength) and/or for the same type of ph meter, I don't see why. Will be ignoring that myself (no Apera replacements on Amazon, either). The calibration solutions will last quite a while, the soaking solution is enough to fill the cap to the mark about twice. 2 reviews for the replacement probe said the glass bulb was too exposed and breaks easily. I disagree - the bulb is inside and above the plastic rim, which does have gaps in the side, but doubt it would break if dropped on flat surface. IP67 means it's dust proof, and can be immersed in up to 1 m of water, or for up to 30 mins, depending on info source. It doesn't mean it's hermetically sealed, though. Overall, the meter seems robust, and looks like it will stand up well to any normal use. So far, would recommend, despite quite high price, as seems well worth it, all things considered. Edit: Have been using this for 6 years now, about once per week, and it still works fine. Have not calibrated it in a while, but it seems to be accurate enough for my purposes (fertiliser/irrigation solution for plants). Like the back-light feature, and it's very easy to calibrate. If it keeps switching to settings screen when you turn it on, it means batteries need replacing, the battery icon does not seem to show accurately. Have so far replaced mine once.
