SPOTTER PLATFORM
Salinity Sensor
Add a compact, inductive conductivity sensor to your Spotter Platform to monitor salinity and water density in real time. Measure conductivity with exceptional stability, minimal drift, and solar-rechargeable power to track ocean mixing and stratification.

Deployment & Best Practices
Configuration Options
Ideal for moored coastal deployments with one Spotter or a network. Integrate up to two more devices (e.g. oxygen/acoustics) per Smart Mooring (max 3 total).
Remote Configuration & Controls
Direct control via Spotter Dashboard, binary/ASCII commands, and Sofar remote support.
Maintenance
Rinse with fresh water after retrieval.
