Optex DOS-20 - Salinity Adjustment

Salinity adjustment
Perform correction for correct measurement of dissolved oxygen density
with a salty solution.
For solutions of the same water temperature, the saturated dissolved
oxygen content (mg/L) decreases as the salt content of the solution
increases. To measure the correct dissolved oxygen density, it is necessary
to correct the salinity even of solution containing salt.
The PSU increments represent the actual salinity increments (not units), and
they are the salinity values converted from the level of electrical conductivity.
Sea water is about 32 to 35 PSU.
