Apera Instruments PH60-Z Smart PH Messgerät (unterstützt durch die ZenTest Mobile App), AI3711

This is a true game changer for pool pH testing. This meter makes pH testing so much faster, easier and more precise. Just have to also purchase the calibration and storage solution refill set and be sure recalibrate it about once every four-six months (this is with daily testing multiple times) and it should last and provide accurate results indefinitely.

Super coole sacher Sehr zufrieden!

This is, of course, brand new so no comment on durability. Seems to work fine, well constructed. Uses AAA batteries which is a positive for me, most use hard to get 'wafer' batteries. Bluetooth connection instantaneous with no problems. However, the software is very non-standard and confusing. It does data log, but log save file function does not work on either of my phones (S23 and S8). Still it is worth it to me since for my application I can't stand next to the process when it is being tested, so I need a remote view function. In addition, only one meter at a time can be monitored. It does flip back and forth between my pH and ORP meter, but it will not do two at once.

Alles bestens, gerne wieder.

Die O-Ringe des Produkts versagen bei dem leichtesten Unterdruck, obwohl diese vor Gebrauch überprüft wurden, sowie nach gängiger Praxis versiegelt.Dadurch versagt das Produkt selbst bei Spritzern.Nicht zu empfehlen.

The meter may be good, but for the totally blind and the Zen app. We cant use it. It would be nice if it was useable without app

Calibration and measurement are straightforward. Once calibrated in the morning, I took several readings of aqueous solutions during the day, and the readings seemed to be OK. I knocked one star off the rating for the fact, that there was black mold in the storage cap for the tip upon arrival. I am aware that the tip needs to be kept moist, but mold can and must be avoided on a precision instrument like this. Now I am worrying about storing the device for longer time during the warmer summer season.

I bought this device for measuring the PH of reverse osmosis water that I give to my plants. The Apera PH60-Z has Bluetooth features which I found appealing, since I like to keep a log of the PH readings. I used the device for less than a year without any problems (simple to calibrate, too). However, last night the device fell into the bucket of water that I was about to PH test, and the top of the device came loose. I should note that this top cap, where batteries and internal circuitry is housed, has NEVER had a tight seal, ever. I have literally never even had to change the batteries, since I’ve only been using the device since Aug 2019 (currently March 2020), so I’ve never had reason to open the top cap, but I’ve noticed on more than one occasion that the cap wasn’t sealed properly after basic use, so I took care to keep it closed and sealed as tightly as possible. I realize now that this was some kind of defect, as it allowed water inside the battery housing and thus has caused the device to go completely haywire. I dried out the insides very thoroughly after it landed in the water by removing the batteries and breaking down the device completely, even using a blow dryer at a distance of several feet away from the device on a no-heat setting (just air, no heat). Once I put thee device back together, the display on the screen is not functioning properly, nor will it connect via Bluetooth to the Zen app.I read through the specs and instructions included with device, and both very clearly state that the PH60-Z has an IP67 waterproof rating, which is defined as: “ IP67 means the unit can be dropped into a body of water up to a meter deep for half an hour, while IP68 guarantees protection in water up to 1.5m deep for the same period of time.”When I contacted Apera (the device is still well within warranty) they told me that water damage isn’t covered, and that’s why it’s important to make sure the device is sealed at all times. This really makes me upset, because I have never mishandled, abused, or neglected this device, and yet they refuse to honor the warranty despite touting the device as IP67 waterproof. What a joke. Apera makes false claims (obviously the device is not waterproof if it can’t survive a VERY quick 1-2 second dunk in a 5 gallon bucket of water) and refused to honor their warranty.I am a founding (and very active) member of one of the most popular and heavily trafficked cannabis grower forums on the web (rollitup.org) and I have a YouTube channel with over 150K subscribers, (in addition to my blog) and I’m going to make sure I let everyone know about the kind of company that Apera is.There are much more scrupulous companies to buy from like Hanna Instruments. Don’t waste your time with Apera.
