The TD-700 Fluorometer is a compact, laboratory fluorometer designed for discrete sample measurement of various fluorescent materials, including chlorophyll, rhodamine, fluorescein, histamine, vitamins, and other fluorescent compounds. When properly calibrated, TD-700 will electronically set the optimal sensitivity and range for your samples and will readout the actual concentration of the compound when in the Direct Concentration mode. The TD-700 can be set up to detect the specific compound you want to measure simply by changing the lamp and optical filters
