Aqua max DO

🧪 What This Data Means — For Quick Client Selection

  • Optical DO Sensor (LDO): No electrolyte, no membrane, no frequent calibration → lowest maintenance cost; ideal for wastewater plants.
  • 0–20 mg/L Range: Covers everything from deep aeration basins (low DO) to fish farms and fermentation (high DO accuracy).
  • ±0.1 mg/L Accuracy: Suitable for process optimization, energy reduction in aeration blowers, and controlled fermentation.
  • Automatic Compensation: Adjusts DO reading for temperature, barometric pressure, and salinity—ensures true DO value.
  • IP65/67 Build: Weatherproof field panel designed for harsh ETP/STP sites with humidity, dust, and chemical exposure.
  • Fast Response: Helps optimize blower speed (VFD control), saving energy in aeration tanks.
  • Reagent-Free Sensor: No consumables → ideal for continuous 24×7 monitoring applications.
  • Digital Output Option: RS485/Modbus enables SCADA connectivity for aeration optimization & real-time monitoring.
  • Industry Fit: Best for municipal STPs, industrial ETPs, aquaculture farms, fermentation processes, and utility DO monitoring.
