Top 5 Best pH Meter

[@rmessenger23]

Putting the Vivosun at #1 making me questioning all of all your resulting stories...

[@SquawkTradeFX]

I purchased two vivosuns to be sure they're accurate. Distilled water that is by default 7 PH measures as 8.3. Both readers were calibrated at the same time. They both have different readings. GAHHBAGGEE

Oh Vivosun, how well you sing your own praises, in perfect Chingrish.

[@Sourdoughgirl]

Exactly.

[@Sourdoughgirl]

Comparison? More like Vivosun advertisement. What a waste of time. LOL

[@bizovski]

Vivosun is 4$ crap you have to calibrate every 5 min ...
