Maintenance
Monthly
•Check level in electrolyte bottle and replace if necessary
Quarterly
•Slightly open the sensor cap of the reference sensor and allow a little
electrolyte (~ 5 ml) to flow out. Fasten cap hand-tight.
•Clean flow cell and flow sensor, if dirty
How to remove and clean Electrodes
A –Connector
B –Electrode
C –Union screw
D –Flow cell block
Note: Do not remove the KCl bottle from its holder or the KCl supply pipe from
the KCl bottle when removing the electrode. Do not put the electrodes into acids
to clean them.
•Unscrew and remove the connector [A] from the electrode [B]
•Unscrew and remove the electrode [B] from the flow cell block by turning the
union screw [C] counterclockwise
•Wipe the electrode shaft and the green tip carefully with a soft, clean, and
damp paper tissue
•Remove grease with a tissue moistened with alcohol
•Slightly open the sensor cap of the reference sensor and allow a little
electrolyte (~ 5 ml) to flow out
•Tighten the sensor cap hand tight again
•Rinse the electrode tip thoroughly with clean water
•Install the electrode into the flow cell again
•Let the electrode run-in for 1 h before the first calibration
A –Sensor cap tightened
B –Sensor cap slightly opened
Calibration
Calibration Video
DO NOT REMOVE TEMPERATURE SENSOR FROM FLOW CELL.
Calibration must be performed with all probes installed in the flow cell block.
Use flow cell vessel to hold calibration standard.
•Calibration must be performed with a clean sensor (and a clean calibration
vessel)
•Calibration solutions must be clean. Do not use if expired
•Always rinse and dry electrodes before immersing them into the calibration
solutions
•Ensure pH standard temperature compensation factors are set up in the
software before proceeding with calibration. See manual for more information
•Navigate to <Maintenance>/<Calibration> and select <Standard pH>. Follow
the instructions on the screen
•Calibration of Standard 1 is successful if the Offset Value is in the range of +/-
30mV
•Calibration of Standard 2 is successful if the Slope Value is in the range of 56 –
61 mV/pH
