immerse the electrode in ph 4.01 or ph 9.18 the standard buffer solution of borax.
after about one minute, until the buffer solution value corresponding to the measurement temperature is obtained.
Important : the instrument¡¯s ph range must be re-calibrated whenever.
approximately one month has passed from the last calibration.
the electrode has been used in particularly taxing conditions.
the utmost accuracy is required.
