Dissolve Oxygen Analyzer

Why Dissolved Oxygen Monitoring Is Important

Dissolved oxygen measurement is essential for maintaining water quality and process efficiency in numerous industries. Oxygen concentration directly affects biological activity, chemical reactions, aquatic life health, and industrial process performance.

A dependable Dissolve Oxygen Analyzer helps industries:

• Maintain water purity
• Improve wastewater treatment efficiency
• Monitor aquatic ecosystems
• Ensure pharmaceutical process accuracy
• Optimize industrial operations
• Reduce operational downtime
• Meet environmental regulations

The DS380 Dissolved Oxygen Analyzer from Zestflow Meters Solutions is specifically designed to provide stable and accurate measurements under varying operational conditions.

Advanced Fluorescence Measuring Principle

The DS380 utilizes an innovative fluorescence quenching technology for dissolved oxygen detection.

How the Measuring Principle Works

The fluorescent dissolved oxygen sensor operates using the quenching principle of specific fluorescence substances in physics.

• Blue light emitted from an LED illuminates the fluorescent material located on the inner surface of the fluorescent cap.
• The fluorescent material becomes excited and emits red light.
• The system calculates the phase difference between red and blue light.
• Internal calibration values are used to determine oxygen molecule concentration.
• Automatic temperature and pressure compensation ensure highly accurate measurements.

This modern fluorescence analysis method eliminates the need for traditional electrolyte-based sensors and significantly reduces maintenance requirements.
