6 Maintenance
6.1 Cleaning the sensor
LCAUTION
Corrosive chemicals
Risk of chemical burns to the eyes and skin and risk of damage to clothing and equipment!
‣It is absolutely essential to protect the eyes and hands properly when working with acids,
alkalis and organic solvents!
‣Wear protective goggles and safety gloves.
‣Clean away splashes on clothes and other objects to prevent any damage.
‣Comply with instructions in the safety data sheets for the chemicals used.
LWARNING
Thiocarbamide
Harmful if swallowed! Limited evidence of carcinogenicity! Possible risk of harm to the unborn
child! Dangerous for the environment with long-term effects!
‣Wear protective goggles, protective gloves and appropriate protective clothing.
‣Avoid all contact with the eyes, mouth and skin.
‣Avoid discharge into the environment.
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.
