Built to Endure:

Fully encapsulated electronics: Protects internal components from harsh environments.
4-20 mA output: Seamless integration with existing data loggers and controllers.
Marine-grade construction: Stainless steel housing for long-lasting performance.
Replaceable DO element: Simplifies maintenance and minimizes downtime.
Understanding Dissolved Oxygen (DO):

Why is DO Important?

DO is essential for aquatic life (fish, plants, etc.).
DO levels reflect the health of a water ecosystem.
What Affects DO Levels?

Oxygen Sources: Atmosphere & photosynthesis.
Oxygen Consumption: Respiration & decomposition.
Pollution: Organic matter increases algae growth, then decomposition depletes DO.
Stratification: Layers of water with varying DO levels.
Temperature: Warmer water holds less DO.
DO Levels & Impact:

5-6 ppm: Ideal for diverse aquatic life.
Below 5 ppm: Stress on aquatic life.
Below 1-2 ppm: Large fish kills can occur.
Additional Tools:

PC320 Dissolved Oxygen Controller: Automates control of pumps or alarms based on DO levels.
GL500 Dissolved Oxygen Data Logger: Records DO data for further analysis.
Maintain healthy aquatic environments with reliable DO monitoring from Global Water!
