Review on FOMOOUR pH Meter - High Accuracy Water Quality Tester - 0.01 pH Measurement Range - Ideal for Water, Brewing, Food, Soil, Sauce, and Laboratory Testing - Includes TDS Meter and pH Pen by Kristin Rogness

Revainrating 1 out of 5

Do not buy: Tried to calibrate, but far from it

Strictly followed calibration instructions. The device never behaved as the instructions said it would (never blinked three times, never read the pH as intended). Then I noticed that the instructions on the listing differ from the printed instructions. There doesn't seem to be a reset button. I tried removing the battery, then it got even weirder. Mostly displays 0000. A piece of junk, poorly designed and documented.

Pros
  • ✔Easy and simple to use: Simply remove the protective cap, dip the PH meter electrode into the solution and press the button to measure. It's damn hard to see the colors of a litmus strip.
Cons
  • Nervous
