Description

The 3919 model is a compact fully integrated sensor for measuring the electrical conductivity of seawater, designed to be mounted directly on the top-end plate of RCM9/11 and RDCP as well as for stand alone operation via the SR10 or RS-232 interface.


Sensor Measurements

  • Salinity (Water)



Notes, Considerations & Recommendations

Conductivity Sensor 3919 is available in three depth ratings as well: 6000m (3919DW; Deep Water), 2000m (3919IW; Intermediate Water) and 300 m (3919SW; Shallow Water).

3919SW/3919IW/3919DW outputs data in both RS-232 and Aanderaa SR10 format. Sensor available in A and B versions; version B has enhanced accuracy compared to version A.

In RS-232 mode the output is: Conductivity in mS/cm, Temperature in deg C, as well as calculated Salinity, Density and Speed of sound.
