PH CALIBRATION
o Immerse the electrode in pH 6.86 (under the temperature of 25°C) standard buffer solution of phosphate, and gently shake it.
o Allow the reading to stabilize and with a small screwdriver turn the calibration trimmer until the display shows is corresponding the calibration solution.
o Immerse the electrode in pH 4.01 or pH 9.18 the standard buffer solution of borax.
o After one minute, until the buffer solution value is corresponding the measurement temperature is obtained.
