Below are listed m-files that I have created and you may find useful. Feel free to download them and use them. The files are provided "as is" and it is up to the user to ensure that the equations in the files are right (although I am confident they are correct, givent their sources - this is just me covering my ass). If you DO find a problem with a file, please let me know (see email below). Also note that these files may change without notice.
probeAB.m: computes the A and B constants for the PME MicroScale Conductivity Temperature Instrument.
probecond.m: computes the conductivity of water using the PME MicroScale Conductivity Temperature Instrument.
probeG.m: computes the gain constant using the PME MicroScale Conductivity Temperature Instrument.
probetemp.m: computes the temperature of water using the PME MicroScale Conductivity Temperature Instrument.
Other files
sal2cond.m: computes the conductivity of a salt water sample from its salinity.
tempc20.m: returns the ratio of the electrical conductance of a salt water solution at temperature 20 C to the electrical conductance of a salt water solution at another temperature.
tempc25.m: returns the ratio of the electrical conductance of a salt water solution at temperature 25 C to the electrical conductance of a salt water solution at another temperature.
