Salinity Sensor

Plug-and-play salinity module for QYSEA FIFISH ROVs (e.g., V6 Expert / Pro V6 Plus), enabling in-situ seawater salinity measurement and logging via the FIFISH app.
Depth-rated to 100 m (328 ft) for coastal, harbor, aquaculture, and research operations.
Real-time readout and recording of total dissolved salt content (ppt) with fine resolution.
Typical measurement range 0–60 ppt (some listings up to 0–72 ppt depending on model/firmware); high resolution to 0.01 ppt.
Simple mounting to the ROV fuselage; power and telemetry through the accessory port.
