Using specific conductance to calibrate data

It is okay to use specific conductance at 25C as calibration points. To calculate specific conductance at 25C from conductivity and temperature, use the attached spreadsheet. The thermal factor of 2.1 is for sea water, mostly sodium chloride (NaCl). Calibration solutions often use potassium chloride (KCl), which has a thermal factor of 1.8.
