Are you tired of constantly replacing electrolyte solutions in your sensors? Or experiencing fluctuating readings that lead to errors in your wastewater treatment analysis? These problems are eliminated when you choose the DS380 DO Sensor (Dissolved Oxygen Sensor)—an intelligent, chemical-free dissolved oxygen sensor utilizing the Optical/Fluorescence method, specifically engineered for rugged environments to deliver precise, stable, and long-term reliable measurements.

Why Optical Technology in DO Sensors Outperforms Traditional Systems

Standard DO sensors on the market typically rely on electrochemical methods, which require frequent membrane and electrolyte replacements. Furthermore, they consume oxygen during measurement, causing unstable readings in stagnant water. In contrast, the DS380 Dissolved Oxygen Sensor operates on the latest Optical (Fluorescence) technology, offering key technical advantages that engineers and operators need to know:

Low Maintenance Requirements: Requires no electrolytes or membrane replacements, and does not consume oxygen during measurement. This guarantees rock-solid, highly accurate readings even in completely stagnant water.
Premium Titanium Housing Material: Engineered with a robust titanium body offering exceptional corrosion resistance. Rated at an IP68 waterproof standard, it can remain submerged in harsh wastewater or aquaculture tanks for extended periods. Maintenance is as simple as wiping down the sensor cap.
Automatic Temperature Compensation (ATC): Features a built-in temperature sensor that automatically calculates and adjusts DO metrics in real-time according to changing water temperatures (0 - 50 °C).
Smart RS485 (Modbus RTU) Connectivity: Transmits crisp digital signals across long distances without data degradation. Seamlessly links with PLCs, HMI screens, or IoT / Smart Farming platforms to monitor data via smartphones or computers instantly.

Technical Specifications

Measurement Range: 0 – 20 mg/L (or 0 – 200% Saturation)
Power Supply: 6 – 12V DC
Output Signal: RS-485 / Modbus RTU
Housing Material: Premium Titanium

Target Applications and Suitable Environments

Wastewater Treatment Systems: Delivers precise control over aerator operations in anoxic/aerobic tanks, preventing energy waste and substantially lowering factory electricity bills.
Aquaculture Industries: Ideal for shrimp and fish farming ponds requiring 24/7 dissolved oxygen monitoring to optimize livestock safety and minimize mortality rates.
Industrial Effluent Monitoring and Environmental Testing: Used to monitor water quality parameters in natural streams or industrial estate water recycling systems to remain fully compliant with strict environmental laws.
