Review on π§ Backlit pH Water Tester for Drinking by Sammie Rodriguez
Meter not working
Meter was calibrated two weeks ago and showed correct pH within a few days. THIS MORNING IT SHOWED A PH OF 13. I TESTED THE PH MANUALLY TWICE AND IT WAS 5.6 TO 6. I DON'T UNDERSTAND WHAT HAPPENED BUT I CAN'T BE SURE THAT THE READING IS. WILL NOT USE ANY MORE.
