Salinity and sound velocity can also be computed. The MicroTSG is constructed of plastic and titanium to ensure long life with minimum maintenance. Additional information available at "http://www.seabird.com/products/spec_sheets/45data.htm" [Summary provided by Sea-Bird Electronics] New Value=Thermosalinograph is an automated Sea Surface Temperature and Salinity measurement system making measurements on board a ship using a water intake. A conductivity cell and a thermistor cell provide conductivity and temperature measurements. Salinity is derived from conductivity and temperature.
