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.

Note: (without the retail box,tks for your well understanding!tks a lot!)

In the following cases, PH meter must be recalibrated:
After calibration has been used (or place) for a long time; Frequent use of special electrodes;
