The 930F model is a variable-wavelength-adjustable fluorescence spectrophotometer, with a standard excitation (EX) wavelength of 365 nm. The 7-inch color touch screen applies professional technology to empower effective human-computer interaction. The USB communication port is used for online operation to facilitate the further calculation and processing of data and time saving, with the universal data processing software package, which is optional.
The instrument is widely used in biochemical, medical, food, environmental protection, chemical and other departments for quantitative analysis. It is an ideal instrument for laboratory and factory inspection.
