Dissolved Oxygen Meters: Accurate Monitoring
for Water Quality Control
“ Dissolved oxygen (DO) is one of the most critical indicators of water quality, affecting aquatic life, wastewater treatment efficiency, and chemical processing. A Dissolved Oxygen Meter measures the concentration of oxygen dissolved in water or other liquids, providing vital real-time data for water monitoring and management.These meters are commonly used in aquaculture, wastewater treatment, laboratories, and environmental monitoring stations. ”

Case Studies
U.S. Case Study 1 – Aquaculture Facility, Florida
A commercial fish farm integrated Enviro Testers’s DO Meters into its water tanks to optimize oxygen supply. Fish survival rates increased by 25%, and energy consumption dropped by 15% due to better control of aeration systems.
U.S. Case Study 2 – Municipal Wastewater Plant, Illinois
Using cloud-connected DO meters from Enviro Testers, a city wastewater plant reduced manual sampling by 60% and improved effluent quality with automated alerts and historical analysis.
Canadian Case Study – Environmental Research Station, Alberta
A university research team used Enviro Testers’s portable DO meters during field studies on mountain lakes. Data accuracy and rugged build ensured reliable readings under extreme environmental conditions.
