Clean away fouling on the sensor as follows depending on the type of fouling:
1. Oily and greasy films:
Clean with fat solvent, e.g. alcohol, or hot water and agents containing surfactants
(alkaline) (e.g. dishwashing detergent).
2. Lime and metal hydroxide buildup and low solubility (lyophobic) organic buildup:
Dissolve buildup with diluted hydrochloric acid (3 %) and then rinse thoroughly with
plenty of clear water.
3. Sulfidic buildup (from flue gas desulfurization or wastewater treatment plants):
Use a mixture of hydrochloric acid (3 %) and thiocarbamide (commercially available)
and then rinse thoroughly with plenty of clear water.
4. Buildup containing proteins (e.g. food industry):
Use a mixture of hydrochloric acid (0.5 %) and pepsin (commercially available) and then
rinse thoroughly with plenty of clear water.
5. Readily soluble biological buildup:
Rinse with pressurized water.
