The meter uses a liquid crystal display for measuring and displaying DO and medium temperature values, with analog and digital signal outputs and control functions.
• Sewage treatment plants:
Oxygen measurement and regulation in the activated sludge basin for a highly efficient biological cleaning process
• Environmental protection water monitoring:
Oxygen measurement in rivers, lakes or seas as an indicator of the water quality
• Water treatment:
Oxygen measurement for status monitoring of drinking water for example (oxygen enrichment, corrosion protection etc.)
• Fish farming:
Oxygen measurement and regulation for optimum living and growth conditions
