## Description

Apera Instruments Premium Series PH60F Flat pH Tester tests pH level for skin, textiles, paper, and other flat surfaces in an reliable and easy manner (Also works great for general water solution's pH testing). Up to 3 points (4. 00, 7. 00, 10. 01) of auto. calibration and 0 to 50˚C Auto. Temperature Compensation (ATC), 0. 01 pH, 0. 5˚C accuracy within -2. 00 to 16. 00 pH measuring range, auto. recognition and reminders of stable values improves consistency, saving you the trouble of guessing when to manually hold measurement (auto. hold function is also available). The product is CE and RoHS certified, and is manufactured under an ISO 9001: 2015 certified quality system.

Review: It works, and works well. - 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.
Review: Great Choice for Hydroponics - Summary I was debating between this brand and one of the more popular brands but ultimately went with this due to the "replaceable" tip. I'm glad I did! Pros - Storage case is substantial - made me feel like I bought a true 'scientific instrument' - Came with all the accessories I need! I guess I didn't read the description carefully, but came with calibration fluid as well as storage fluid. There was also a lanyard. - Easy to use! Right off the bat, the device was already calibrated at the factory using all 3 PH values for reference. There is even a certificate certifying the same. I did my own calibration, though, and it was easy to do! (The drawback to doing your own calibration is you'll need the PH 10 reference fluid to complete the trio of calibration. Out of the factory all 3 were done and you'll see an icon L, M, H indicating this. If you do the PH 4 and PH 7 calibrations, you'll get L & M but no H. I'm OK with this but if you need super precision, something to keep in mind.) - Seems accurate based on my drop tester readings (which aren't as accurate because I have to compare color codings). I don't have another reference point so this is my opinion. Cons - As someone else mentioned, the backlight doesn't stay on very long. Not really a true Con for me as I don't need it under the conditions I operate in, but it would be nice to have a setting to adjust how long it stays on. - The storage solution is nice! I ended up using the entire bottle pretty quickly. 2x the size might be nice. It apparently lengthens (or cleans) the probe so I always store it in the solution. The solution seems to rapidly dissipate for whatever reason. More can be bought on its own, however. All in all I am very pleased with this tester. It fits my requirements for hydroponics and nutrient measurements. It was a great price and came with all you need to get started.

### ⭐⭐⭐⭐⭐ Quality Instrument
*by A***R on November 17, 2024*

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.
