There are two basic types of fluorometers, the filter fluorometer and the spectrofluorometer. Chlorophyll fluorescence can easily be measured with a chlorophyll fluorometer. The degree of protection is quantified using a fluorometer. Additional scientific equipment included a thermosalinograph and a fluorometer. A filter fluorometer will use filters while a spectrofluorometer will use grating monochromators. A filter fluorometer is a type of fluorometer that may be employed in fluorescence spectroscopy. If filters are used to select wavelengths of light, the machine is called a fluorometer. LS-2, Perkin-Elmer Luminescence Spectrometer Model LS 5, and LKB-Wallac Time-Resolved Fluorometer Model 1230.
