ABB ADS420 Dissolved Oxygen Probe

ABB ADS420 Dissolved Oxygen Sensor – Accurate, Optical DO Probe for Industrial & Wastewater Applications

Buy ABB ADS420 Optical Dissolved Oxygen Probe – Trusted Supplier in Saudi Arabia, UAE, Qatar, Oman, Bahrain & Kuwait

The ABB ADS420 is a next-generation optical dissolved oxygen (DO) sensor engineered for precision, reliability, and intelligent performance in harsh process environments. Designed with advanced dynamic luminescence quenching technology, it provides drift-free measurements, fast response times, and minimal maintenance—making it ideal for continuous monitoring in wastewater treatment plants, industrial processes, and environmental water quality systems.

Fully compatible with ABB’s multi-input transmitters, the ADS420 supports plug-and-play installation, automatic sensor recognition, and predictive diagnostics via Memosens technology—delivering smarter control, reduced downtime, and enhanced process efficiency.

🔧 Key Features & Advantages:

• Advanced Optical Measurement:
  Utilizes dynamic luminescence quenching for highly accurate, reagent-free dissolved oxygen analysis.

• Stable & Drift-Free Operation:
  Delivers long-term measurement stability without frequent recalibration.

• Rapid Response Time:
  Provides real-time feedback for process optimization and control.

• Smart Sensor Technology:
  Features auto-recognition, plug-and-play setup, and predictive diagnostics for proactive maintenance.

• Wide Measurement Range:
  Measures DO concentrations from 0 to 50 ppm (mg/L), suitable for diverse process needs.

• Rugged & Durable Design:
  Built to resist abrasion, photobleaching, and extreme environmental conditions.

🧪 How the ADS420 Works:

1. Excitation: A blue LED excites lumiphore molecules in the sensor cap.

2. Emission: The excited molecules emit red light detected by a photodiode.

3. Quenching: Dissolved oxygen interacts with lumiphore molecules, reducing emitted light.

4. Calculation: The phase shift between emitted and reference light is measured to determine DO levels.

🌍 Applications:

• Wastewater Treatment Plants:
  Optimize aeration control, improve energy efficiency, and maintain ideal DO levels for biological processes.

• Industrial Process Monitoring:
  Ensure accurate oxygen control in food, beverage, chemical, or pharmaceutical production.

• Environmental & Aquatic Monitoring:
  Track dissolved oxygen in rivers, lakes, and reservoirs to detect pollution and protect aquatic ecosystems.
