Currently NO - pH meter

It does not recognize any calibration liquid other than 6.86, it will not calibrate to 4.0 or 9.18. I want a replacement or a full refund ASAP, fuck it, that's not going to work

Pros
  • Robust construction
Cons
  • ---

Exactly what I needed:

Great help finally getting my CO2! After calibrating with the supplied solution, this little device helped me achieve a 1-point drop in pH that was not possible with standard test kits.

Pros
  • Best in niche
Cons
  • Sad equipment

Good price for a good tool

Poorly translated instructions seem to be typical these days. It's actually getting old, but I digress. Accurate, no more difficult to calibrate than any instrument of its kind. Measures pH and does it well.

Pros
  • Dope 🔥
Cons
  • Mostly ok but...

Calibrated incorrectly

Received last November, unused until January 2nd, thought something was wrong due to the amount of caustic needed to raise the pH. In the past, our water was always too high. When attempting to recalibrate, it was found that when the tester was placed in a pH 9.18 solution, it calibrated to pH 6.86, not 9.18. I tried everything, changed batteries and solutions, nothing helped.

Pros
  • Industrial & Scientific
Cons
  • Incredible piggy bank

The calibration algorithm is screwed up

We were a bit disappointed with this counter, so I decided to calibrate it. Big mistake. It randomly picks the wrong point to calibrate. In a buffer with a pH of 6.86, he usually chooses a value of 9.18. In a pH buffer of 4.01, he usually chooses 6.86, but sometimes 9.18. From time to time one of the calibration points gets correct, but then when I try to calibrate pH 4.01 it distorts the whole calibration curve. I compare it to a pH 7.00 reference solution and get 7.34. The counter can no…

Pros
  • Test, measure and verify
Cons
  • New competitors have appeared

Calibration failed in a week! Recalibration failed

This device seemed promising at first. I did the initial pH calibration using different buffer powders and distilled water. Well calibrated and delivered stable results compared to the test strip. It was used to read the pH of the water in an aquarium. In less than a week, I noticed that the readings were actually different than I expected. I checked it again against the test strip and it really wasn't the same as before and clearly out of calibration already. When I tried to recalibrate with…
