Salinity Correction Factors
Use the values in Table 12 if you do not have a conductivity
probe. Use a conductivity meter to obtain conductivity in mS/cm
at reference temperature (20 °C), then use Table 12 to estimate
the salinity correction factor (in ppt*) to the nearest whole
number. Enter the salinity value from Table 12 into the meter per
the setup function in Section 5.2 on page 49.
This table was calculated up to the conductivity of 54 mS/cm
from the International Oceanographic Tables**.
*Salinity determined by the conductivity at 20 °C.
* ppt = Parts per Thousand of Salinity
** International Oceanographic Tables, Vol. I, National Institute of Oceanography of Great Britain,
Womley, Godaming, Surrey, England and Uncesco, Paris 1971.
