The resistivity is inversely © 2000 M. Tomczak. As temperature is important in salinity calculation (usually measured at 25ºC), most EC meters have built-in temperature compensation. All can be used to calculate salinity. according to the above formula. Total dissolved solids (TDS) and total soluble salts (TSS) are measured by different processes, but can be generally thought of as the same. Calculation based on Fofonoff, P. and R. C. Millard Jr (1983) Algorithms for computation of fundamental properties of seawater. Conductivity (mS/cm) = Temperature (ITS-90) = Sea Pressure (dbar) = Practical Salinity (PSS-78) = Search for: History of Salinometry. Capacitance Calculator Ion exchange calculator. Resitivity & Conductivity are the basic properties of electricity that determines how strongly a material opposes or how easily passes the flow of electric current through it. Practical Salinity Calculator. The quantity used in the determination of salinity in bench salinometers is the conductivity ratio Rt(S,t) = C(S,t,0) / (C,35,t,0) where S is salinity, t is temperature and C is conductivity. We want to work with you, and offer our skills and knowledge to help you get the best outcomes. Salinity Calculator This calculator derives salinity from a value of the in situ conductivity (as determined, for example, by a CTD), temperature and pressure. Salinity Conversion Calculator This calculator converts between various units of salinity. Absolute salinity is reported in g/kg and is denoted by the symbol S A. TEOS-10 offers pre-programmed equations to calculate absolute salinity. Total dissolved solids (TDS) and total soluble salts (TSS) are measured by different processes, but can be generally thought of as the same. The greater the length of the material, the lower the resistivity. carbonate and bi-carbonate salts, magnesium and calcium sulfates, potassium).

Salinity (PSS-78) = Temperature (ITS-90) = Sea Pressure (dbar) = Conductivity (mS/cm) = Search for: History of Salinometry. The inverse of resistivity is This means that water samples can be measured quickly and accurately in the field. Use spreadsheet or calculator to convert conductivity and temperature data to salinity value.
