Apera InstrumentsPH60-HT Handheld pH Meter Tester Kit with LabSen 865 pH/Temp. Electrode for Lab-Grade pH Measurement in High Temperature and/or Corrosive Water Solutions

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to be well made - so I think it should last well if treated with the care something like this deserves.They do have a newer version of this that has bluetooth and a "new improved sensor".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 recently purchased this Apera PH60 pH Tester for General Purpose in order to test a variety of home foods, drinks, toothpastes, mouthwashs, etc. The intent is to better manage dental health (tooth enamel erosion) by avoiding acidic items as much as possible. As a retired chemist, I understand pH principles and how to properly treat meters, measuring probes, and aqueous test samples.I've used this PH60 tester across most of the pH spectrum (0-14) in aqueous liquids, pastes, and gels over the last few weeks now, and have been pleased with the overall performance. The 3-point auto buffer calibration is quick and easy, and sample readings usually stabilize within seconds. The backlit screen makes it easy to read pH value (with smiley face confirmation of stability), sample temperature, and which buffers were used during last calibration. It's nice knowing this device has the automatic temperature compensation (ATC), since pH is temperature dependent.Immediate and thorough cleaning of critical measuring structures at probe tip (glass sensing bulb and porous reference junction) is, of course, essential, and this has been easily accomplished using distilled water in a 16 loz LDPE squirt bottle (separate purchase). The delicate glass sensing bulb is protected within a cage of plastic, but can easily be accessed by removal of probe cap.This tester is a nice, convenient pocket size, and its plastic body appears to be waterproof. The plastic carry case seems well built and securely holds all the necessary calibration liquids and containers. A relatively simple, compact, conveniently portable pH measuring system good for home or lab use.Given its reasonable price and my hassle-free, positive results thus far, I would definitely recommend.

SummaryI 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.

No lo he probado, tampoco ensendido, pero el estuche y al abrirlo, de muy buena calidad

Bra kvalitet

The readings settle quite quickly and the built in temperature element corrects the pH for temperature saving that extra step.The instrument is robust and feels well made.I am pleased with it.

Recently I had the occasion to do some online research to purchase a digital pH meter for my hot tub. I wanted to validate the readings that I was getting from my hot tub online and on the top deck display, and for months had been using the liquid reagents to test. I wanted something accurate that would give me a relatively instant and proper pH reading, and not have to play the difficult game of guessing with the difficult colour matching that I had to do with the liquid reagents.The name Apera kept coming up in some of the online comparisons I was reading on portable digital pH meters, and so I decided to go with the Apera Instruments PH60 Premium Waterproof pH Pocket Tester. Very impressed! Although it may seem pricey when compared to other available portable digital pH meters, it is more than worth the difference in dollars, which really isn't that great anyway, especially when you consider the quality and build on this unit. It all comes together in an excellent high-quality case and comes with the necessary storage fluid and calibration fluids to calibrate when necessary for accurate results.After a small hiccup with the first unit that Amazon Canada had shipped me (the first unit received had obviously been used), I received the replacement Apera meter and case a couple of days later. Thank you, Amazon, for your extremely easy return policy ... but most of all ...Thank you Apera Instruments for a high-quality, accurate, and easy to use portable pH meter that frees me from having to validate using liquid reagents! Highly recommended!
