DST CT Conductivity, Salinity and Temperature Data Logger

Reference: DST CT
Brand: Star-Oddi

The standalone conductivity data logger DST CT measures and records conductivity and temperature. Upon data conversion, the software calculates and displays the salinity values and velocity with a time stamp. Size is only 46 mm in length and 15 mm in diameter.

For use on subsea moorings, underwater equipment and water quality monitoring. Adding Star-Oddi’s protective housing offers flexible mounting of the conductivity meter.
