The JRCS JMC-SMS-25 is a high-precision Salinity Monitoring System designed specifically for demanding marine environments. It plays a crucial role in Ballast Water Management Systems (BWMS) by accurately measuring the salinity of the water, enabling the system to differentiate between seawater, brackish water, and freshwater. This essential data ensures the BWMS operates effectively and in compliance with international maritime regulations. The system consists of a robust sensor unit and a clear, easy-to-read indicator panel, providing reliable and continuous monitoring. With standard analog and contact outputs, the JMC-SMS-25 integrates seamlessly into a vessel’s existing alarm and control systems, enhancing operational safety and environmental protection.
