2.2 Designated use
The oxygen sensor is suitable for continuous measurement of dissolved oxygen in water.
The main areas of application are:
• Wastewater treatment plants
– Oxygen measurement and regulation in the activated sludge basin for a highly efficient
biological cleaning process
– Monitoring the oxygen content in the wastewater treatment plant outlet
• Water monitoring
Oxygen measurement in rivers, lakes or seas as an indicator of the water quality
• Water treatment
Oxygen measurement for status monitoring, e.g. of drinking water (oxygen enrichment,
corrosion protection etc.)
• Fish farming
Oxygen measurement and regulation for optimum living and growth conditions
Use of the device for any purpose other than that described, poses a threat to the safety of
people and of the entire measuring system and is therefore not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.
