Based on the fluorescence characteristics of chlorophyll-a ,this paper reports a mast on-line fluorescence instrument for determination of chlorophyll-a.This instrument uses the ultra-high brightness light emitting diode (LED) with wavelength of 470 nm as the excitation light source ,and is equipped with the advanced fluorescence signal detection system.The working depth of the fluoro probe is up to 100 m. A comparison between the results of chlorophyll determinations made on a suite of marine samples by the flu-orometer and the spectrophotometry show s little significant difference.
