Calibrating Oxygen Sensors with Temperature
Compensation
Perform the steps below to calibrate your oxygen sensors using temperature compensation.
About Factory Calibration
If you want to compensate for temperature changes, you can purchase a Factory Calibration to be
performed at Ocean Optics prior to shipping the Fiber Optic Sensors System. Consult an Ocean Optics
catalog, contact an Ocean Optics Applicati
for a price for this service.
Note
Factory Calibration can only be performed if you specify the oxygen concentration range and
temperature in which you will be working when you purchase the Fiber Optic Sensors System.
Calibrating With Factory Calibration
Perform the steps below to calibrate the oxygen sensors for temperature compensation using the factory
calibration.
Note
If you are not using (or do not have) a factory calibration file, proceed to
later in this chapter.
Preparing for Calibration Using the Factory Calibration
If you ordered the Factory Calibration, you are provided with an additional file that includes data for the
Calibration Table. You will need this file in Step 5.
►
Procedure
1. Set the data acquisition parameters for the calibration procedure (integration time, averaging, and
boxcar smoothing).
2. Set the integration time for the entire calibration procedure when the probe is measuring the
standard with zero concentration at the lowest sample temperature you will be using. The
fluorescence peak (~600 nm) will be at its maximum at zero concentration.
