gives poor readings even when calibrated and packs up within a month
Even straight after calibrating this was about 5 points off no matter how many times i recalibrated and within a month of use it just started throwing up random numbers,I did keep it in storage solution and used a PH meter cleaner,It was giving readings like 9.0 for distilled water.More landfill crap

Not clear at all.
Couldn’t understand the instructions nor the readings. Returned and bought a more expensive one that had ‘normal’ readings! Seller got in touch and sent a replacement foc. Very kind of them but the instructions are no clearer. Until the writhing is enlarged, I can’t give a better review.

La calibration est simple. Par contre, par rapport à une sonde témoin, il est extrêmement lent. Il faut compter presque 10 minutes pour que le pH final soit affiché. Il faut donc le mettre longtemps pour à avoir le bon pH. Après 6 mois et une utilisation par mois, il deconne complètement. Mauvaise qualité

This is the second of these PH meters I've purchased. There are a number of negative reviews, so I was a little concerned but went ahead and order one. The first meter calibrated easily and (apparently) accurately. I used the three point calibration, then tested my fish tanks and compared the reading to the drop type ph test kit I had been using. It was spot on as close as I could tell with the test kit. I used the meter for a week, every day on several tanks as I changed the ph. It tracked these changes as I would have expected it to. It worked very well for me so I ordered a second PH meter. (I have fish tanks in two locations.) I then used these two meters side by side. They vary from each other by 0.10 points. The second meter did not calibrate as easily as the first, and the calibration was off slightly. I will try recalibrating, but it's as accurate as I need now. I'm very satisficed with them and would recommend.
