Maintenance of pH sensor

Clean

pH sensor

Remove the pH sensor [B] from the flow cell.

Unscrew and remove the connector [A] from the pH sensor.

Prevent the connectors from getting wet

If necessary wipe the pH sensor shaft and the green tip cau-

tiously with a soft, clean, and damp paper tissue.

Remove grease with a tissue moistened with alcohol.

CAUTION: Alcohol is inflammable.

If the sensor is very dirty put it into 1% diluted hydrochloric acid

for 1 min.

CAUTION! hydrochloric acid is corrosive!

Rinse the pH sensor with clean water.
