SECTION 9 REFERENCE TABLES
The following tables have been provided as a reference, but are
not required for use with the DO meter.
9.1 Salinity Correction Factors
Use the values in Table 7 if the conductivity meter in use does not
measure salinity. Use a conductivity meter to obtain conductivity
in mS/cm at reference temperature (20 °C), then use Table 7 to
estimate the salinity correction factor (in ppt*) to the nearest
whole number. Enter the salinity value from Table 7 into the
meter per setup function Section 3.1.4 on page 24.
This table was calculated up to the conductivity of 54 mmhos/cm
from the International Oceanographic Tables**.
*Salinity determined by the conductivity at 20 °C.
* ppt = Parts per Thousands of Salinity
** International Oceanographic Tables, Vol. I, National Institute of Oceanography of Great Britain,
Womley, Godaming, Surrey, England and Uncesco, Paris 1971.
