If the sensor needs to be stored or transported, follow the procedure below:
Procedure for storing the sensor and period of non-use:
- The sensor must be stored correctly when the equipment is not being used or if the system will have no flow for more than 4 days.
- Use a small screwdriver or similar tool to remove the transparent cover [13] protecting the bleed hole [12], and move it to one side so that
the bleed hole [12] is accessible.
- Unscrew the membrane head [15] from the sensor body [7].
- Rinse the active parts of the sensor [10,11] with distilled water, removing any remaining electrolyte, and allow them to dry.
- Once dry, screw the membrane head [15] carefully onto the sensor body. The membrane [14] must not touch the sensor electrode [11], as
this would damage it and render it unusable.
Reusing the sensor after prolonged storage:
- Clean the sensor electrode [11] as described above with the special sandpaper provided.
- Replace the membrane head [15] with a new one, following the procedure described above.
