Citadel TS-NH

The Teledyne RD Instruments CITADEL TS-NH THERMOSALINOGRAPH is a compact, low-maintenance system with exceptional stability for monitoring sea surface salinity, as well as sound velocity and water density.

The Citadel TS-NH Thermosalinograph uses Teledyne RDI’s patented NXIC (Non-eXternal Inductive Conductivity) sensor and an aged thermistor to provide precise conductivity and temperature measurement, resulting in high-accuracy calculated salinity, sound velocity, and density.

The system is cast in a urethane mold, and the electronics are housed in an integral sealed (moistureproof) housing. The unit is easy to install and remove on in-line piping using either 3/4" hose pipe barbs or optional threaded fittings, and is easily integrated into larger ferry box systems providing additional biological and chemical measurements.?
