Oxix in salinity applications
A salinity correction factor is entered as follows:
• The sensor is measuring. The current measurement is shown in line 2
(10.20 mg/l in this example).
• Set the desired salinity correction factor on the first line using the up and
down arrow keys. The interval is from 0.500 to 1.500.
• Save the current correction factor setup by pressing OK.
When measurement is done in the ppm or mg/litre units, a salinity correction
is required (not when measuring in % SAT!).
The correction factor for the current application is found in a matrix with fac-
tors for different salinity levels, where the salinity level is shown by electrical
conductivity.
It is assumed that the salinity level in the application is stable, as the factor
can only be entered manually. Alternatively, Oxix can be used without cor-
rection factor and in itself correct the DO measuring based on the measured
conductivity by third-party equipment.
