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.
