SUP-DM2800 Dissolved Oxygen Meter

UP-DM2800 Dissolved oxygen is the measure of oxygen dissolved in an aqueous solution. Polarographic measurement principle, the dissolution value depends on the temperature of the aqueous solution, pressure and salinity in solution

Categories: ,

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
Host is fixed: the transmitter can be Paneled, Piped, wall-mounted installation.
Panel installation: requested to stay in the power distribution box on the Panel 138X138mm Square hole, the transmitters are attached to cage back into, and 4 M5 tighten screws.
