Procedure
1 Remove the electrode protective cover, will PH electrode into the
electrode \'s BNC connector socket .
2 Rinse the electrode with distilled water and dry with filter
paper attached to the electrodes of the water.
3 Touch the " " switch boot, tap "℃ / ℉" key to switch to
Fahrenheit Celsius .
4 pH meter electrode into the test solution and gently stir until
the numerical stability , read the display ( NOTE: The display on
the row for the pH value , the lower the temperature value ) .
5 After use, clean the electrode , touch " " switch off , put the
electrode protective sleeve.
pH calibration
1 . The pH electrode into a pH of 6.*6 ( the temperature at *5 ℃)
standard mixed phosphate buffer solution, gently shake the
electrode .
(2) with a small screwdriver to adjust the potentiometer until the
display value and the standard buffer solution at ambient
temperature pH values.
3 . The pH electrode immersed in pH4.*1 phosphorus or potassium
hydrogen phthalate standard pH9.*8 borax buffer solution , gently
shake the electrode .
4 shows the pH value of the buffer value is compared to the error
should be within the allowable range .
Precautions
In the following cases , the instrument must be recalibrated .
After calibration has been used ( or place ) for a long time
Frequent use of special electrodes
Accuracy requirements are relatively high .
Battery Installation
