Cleaning the assembly
To ensure stable and reliable measurements, the assembly and the sensor must be cleaned
regularly. The frequency and intensity of the cleaning process depend on the medium.
A typical example of a cleaning interval would be 6 months in the case of drinking
water.
Cleaning the assembly
1. Remove light dirt and fouling with suitable cleaning solutions.
2. Remove heavy soiling using a soft brush and a suitable cleaning agent.
3. For very persistent dirt, soak the parts in a cleaning solution. Then clean the parts
with a brush.
