Community Standard Description
(http://vocab.nerc.ac.uk/collection/L22/current/TOOL0172/)
Instrument Description:

The Environmental Characterization Optics (ECO) series of single channel fluorometers delivers both high resolution and wide ranges across the entire line of parameters using 14 bit digital processing. The ECO series excels in biological monitoring and dye trace studies. The potted optics block results in long term stability of the instrument and the optional anti-biofouling technology delivers truly long term field measurements.

Dataset-specific description

Calibration page for first  fluorometer.

"The primary fluorometer was mis-calibrated (had the wrong scale factor in the calibration/processing file), so fluorescence data from the first four (or five) stations (Stns #22, #7, #8, #11) had to be re-processed with the correct scaling factor. Examination of the *.cnv file showed which casts had the miscalibrated data, as the max reading for fluorescence was ~ 0.05 mg/m3. For nearly every other station, maximum fluorescence readings were > 1.0 mg/m3. A secondary fluorometer was added to the CTD rosette between Stns #11 and #12, which verified that the issue was with the scale factor in the CTD processing software." (from Cruise Report)

The Default Scale Factor in the Calibration sheet, 25, is the correct scale factor and was not the one used for the first four CTDs. (2,3,5,6 from stations 22,7,8,and 11, respectively)  The fluorescence in those casts should not be used until corrected.
