Below are the steps i have followed to get DO Values in mg/L ,I am not sure whether its correct or not .Please suggest me the best way to calculate DO or any formula to get DO values from mV output .
Step 1.Measure mV from sensor .
Step 2. Calculation of % Saturation :
%Saturation = (mV in water/mV in air) * 100
Step 3.Measurement of DO(mg/L)
DO= % saturation *correction factor from DO manual chart(salinity ,pressure and temp relation) .
To Measure DO ,we need to calculate Atmospheric Pressure ,Salinity and Temperature .
Que:How to determine Pressure ,Salinity and Temperature ?
Step 4.correction factor .
How to calculate correction factor from table ?
PFA datasheets of sensor.
