13.1.3 Maintenance:
Depending on the type of environment, periodically rinse the probe thoroughly with a water jet, particularly
focussing on the insides of the optical measuring channel.
Never use hard, pointed, rough or blunt objects such as wire brushes, cutters, screwdrivers, knives,
and scrapers to clean the SS sensor. This may damage the probe and scratch the optics or remove
their polish.
Preferably use a soft cloth or paper towel soaked in alcohol to clean the SS sensor optics. Never
scrape or scratch the glass optic windows: Soak them for 1 hour in clean water, surface active
agent + diluted scale inhibitor (for dry dirt layer and limestone deposits) solution.
Advice: For better cleaning results, finish cleaning by rubbing both windows with alcohol-soaked
cotton buds.
Recommended cleaning frequency:
For urban wastewater treatment active sludge, it is recommended to clean the optics every two weeks.
Comment:
The best possible cleaning frequency for optics in this kind of probe can only be determined through
experimentation as the dirt level depends on several factors which vary according to sites, processes, sludge
quality, hydraulics, etc.
This frequency may be increased from one week to one month as the case may be.
If you notice a lot of damping in the measurements:
-
Clean the SS sensor (especially the optics)
-
Zero calibrate in clean water
