Dissolved Oxygen Flowcell – Fig 2.7
Allow sufficient clearance (200 mm all around) for easy removal
of the flowcell assembly for maintenance when not installed in
the optional enclosure – see Section 2.3.1 for overall dimensions
of units.
Note.
To eliminate the risk of bubbles accumulating at the
sensor, and hence giving erroneous readings, the flowcell
assembly must be mounted vertically.

level thus allowing an unrestricted view of the front panel
displays and controls.
