Salinity
Section 4
YSI, Incorporated
Model 52
12
Even if your sample is saline, it is still best to calibrate in air. However, if you must
calibrate in air-saturated water, it is best if the calibration sample is similar to the sample
you intend to measure. Disregard the mg/L reading when measuring non-aqueous liquids.
Such samples may have an oxygen solubility or Bunsen coefficient significantly different
from those used in the Model 52.
Note: If you are calibrating in mg/L, the salinity must be set before calibration.
If you are calibrating by a Winkler titration, the salinity of the calibration sample must be
the same as that of the samples you intend to measure. It is not necessary to know the
salinity value, only that it is the same in both the calibration and measured samples. You
must not change the salinity setting after calibration. If you do change it after a mg/L
calibration, you must recalibrate.
After calibrating, switch to O

-TEMP. The display will simultaneously show temperature,
% air saturation, and oxygen concentration.
