PH meter calibration while increasing standards:
  • 1, the pH electrode into the pH value of 6.86 (25 oCc under standard mixed phosphate buffer solution, and gently shake.
  • 2, with a small screwdriver adjust the calibration potentiometer until the display value and the standard buffer solution at ambient temperature ph values.
  • 3, the electrodes into pH4.00 stupid phosphorus or potassium acid borax pH9.18 standard buffer solution.
  • 4, after about two minutes or so. Shows the pH value of the buffer value is compared to the error should be within the allowable range.
