DO concentration - Weiss

The equation by Weiss is used to convert saturation to concentration for the instruments using Oxyguard, Aanderaa, and Rinko sensors. The equation reads:

where:

A_l = -173.4292                 
A₂ = 249.6339                     
A₃ = 143.3483
A₄ = - 21.8492                 
B₁ = - 0.033096
B₂ =   0.014259
B₃ = - 0.001700

S = salinity in g/kg

T = temperature  degrees K

Temperature in degrees Kelvin is calculated using equation [2].
