Digital RS485 Four-Electrode Conductivity Salinity Sensor For Seawater

Digital RS485 Four-Electrode Conductivity Salinity Sensor For Seawater

Daruifuno DEC360: High-Precision Digital Conductivity and Salinity Sensor
The Daruifuno DEC360 digital flat-head, four-electrode sensor offers precise measurement of both conductivity (0-200 mS/cm) and salinity (0-100 ppt). Engineered with a titanium alloy shell, it boasts exceptional resistance to high pollution and corrosive seawater environments, making it ideal for demanding applications.

This versatile sensor is widely adopted in critical areas such as industrial water treatment, sewage monitoring, drinking water analysis, and chemical process control, where accurate conductivity measurements are paramount.

Its innovative flat-head design simplifies installation and flushing, effectively preventing scaling and ensuring consistent performance. The DEC360 is perfectly suited for installation in circulation pools, pipelines, or immersion scenarios. Furthermore, it features built-in digital communication (e.g., RS485 MODBUS), providing superior anti-interference capabilities compared to traditional analog 4-20 mA outputs, and enabling reliable long-distance communication.

Features＆ Advantages

• IP68 Protection: Built to last, this sensor boasts an IP68 protection rating, allowing for continuous, long-term underwater operation without compromise.
• Titanium Alloy Construction: Crafted from titanium alloy, the DEC360 offers an exceptional combination of lightweight design, high strength, and superior corrosion resistance. Its excellent biocompatibility makes it perfectly suited for harsh conditions, including seawater, acids, and alkalis, ensuring a prolonged service life and stable, highly accurate measurements.
• Advanced Measurement Capabilities
• Superior Anti-Pollution: Unlike traditional two-electrode sensors, our four-electrode conductivity technology effectively eliminates polarization effects. This design significantly reduces interference from scaling, oil, and electrolysis byproducts, making the DEC360 highly resistant to pollution and ideal for high-conductivity or heavily contaminated media.
• Broad Measurement Range: The DEC360 offers a versatile wide range for both conductivity and salinity measurements. It precisely detects conductivity from 1 μS/cm to 200 mS/cm and salinity from 0 to 100 ppt (‰).
• High Linearity & Stability: The innovative four-electrode configuration prevents the influence of electrode polarization and contact resistance. This results in highly stable and reliable measurement results with a faster response time, ensuring superior accuracy.
• Automatic Temperature Compensation: Featuring a built-in temperature sensor, the DEC360 provides automatic conductivity temperature compensation, significantly enhancing measurement precision across varying temperatures.
• Enhanced Usability & Communication
• Digital Anti-Interference Output: With digital communication (e.g., RS485 MODBUS), the sensor delivers strong anti-interference capabilities and supports reliable long-distance communication, surpassing the limitations of traditional analog outputs.
• Easy to Clean Flat-Head Design: The flat-head design is specifically engineered to resist impurity accumulation, which reduces the frequency of manual cleaning and minimizes maintenance. This makes it highly suitable for integration into automated systems and ensures strong resistance to pollution.
