SBE 16 Oxygen Saturation

Overview

Dissolved Oxygen and Oxygen Saturation are computed according to the algorithms provided in Application Note NO. 64 - SBE 43 Dissolved Oxygen Sensor.

OXSAT(t,s) = exp[A1 + A2*(100/t) + A3*ln(t/100) + A4*(t/100) + s*(B1 + B2(t/100) + B3*(t/100)*(t/100))]

Input

  1. temperature in ° K = ° C + 273.15

  2. salinity (PSU)
