5.4 Replacing desiccant
The ULTRATURB sc turbidity sensor is continuously subject to a wet environment.
To provide protection against the moisture, there are 2 generously sized desiccant
bags close to the optical and electronic components. To maintain this protection,
the manufacturer recommends replacement or regeneration every 2 years.
To replace the desiccant, open the housing and replace the two desiccant bags,
4 units (see
Figure 6 , item 1) and 0.5 units (see Figure 6 , item 2) as per the figure.
