become generally unreliable and unrepeatable (unless taken under ideal conditions) due to
interfering factors such as refraction from visible air bubbles and microscopic aeration.

25.5. What is the Accuracy of the Optical Probes?

All Optical Probes, with the exception of the Turbidity Electrode, employ
fluorescent measurement techniques. Interference from microbiological species
and compounds which fluoresce at similar wavelengths and differences in
fluorescence caused by temperature, ambient light and turbidity can all cause
inaccuracies.
Fluorescence measurement is ideal for researchers who are interested in
detecting the presence or absence of a specific substance in reasonable
concentrations and measuring relative fluorescence changes that can be used
as an indication of increasing or decreasing concentrations.
Fluorescence measurement
measurement and it is therefore impossible to specify an absolute accuracy.
In order to obtain accurate results, data obtained with a fluorescent
electrode in the field must be post-calibrated with data from standard
laboratory analysis of grab samples acquired during the study.
