Online Water Salinity Sensor, 0~70PSU, RS485

Online water salinity sensor is a high-precision online water quality analysis sensor. It employs the electrode method for measurement and is suitable for applications in environmental protection and water conservancy (surface water), water supply and wastewater treatment, modern agricultural water quality management, industrial automated water quality monitoring, and marine environment and ship monitoring. SUCH salinity sensor has a measurement range of 0~70 PSU, a resolution of 0.1 PSU, and an accuracy of ±1.5% F.S. It features two-point calibration and supports RS485 output. The device can operate stably at 0~65℃ and <0.6 MPa, with power consumption as low as 0.2W@12V. The housing is made of ABS material, achieving an IP68 protection rating.

Feature

• Electromagnetic Electrode Design: Utilizes magnetic field induction for high sensitivity, stable signals, and accurate measurements.
• Sealed Waterproof Structure: Waterproof connectors ensure uninterrupted signal transmission and reliable long-term monitoring.
• Corrosion-resistant and Easy to Clean: The sensor surface resists fouling and corrosion, making maintenance simple and efficient.
