Awesome thanks!It should work, just make sure it's calibrated obviously.
It's also probably a good idea to compare it to another ph test kit.
I've had a bad experience with an uncalibrated "yellow" ph tester
Well crap sandwichI had exact same one. I did 2 point calibration but it read kalk solution lower than tap water. In garbage it went. [all the readings were always around 7.7pH no matter what I was testing]. Hopefully yours will work better.
