SED-1100FGDJ2-B UV-Visible Spectrophotometer — double-beam optical path design with 1200 lines/mm UV-dedicated holographic grating, 1.7 nm spectral bandwidth and 190–1100 nm wavelength range. Standard 8-position automati
مبدأ العمل
Double-beam dispersive UV-Vis: light from the imported D2(UV) and tungsten(visible) lamps is dispersed by a 1200 lines/mm UV-dedicated holographic grating; the monochromatic beam is split into a sample beam and a reference beam simultaneously measured by photoelectric converters. Ratio detection eliminates source-drift errors. The 7-inch touchscreen HMI with large-scale IC provides intelligent, automated operation. Auto features include wavelength error correction, 8-position auto cuvette changer, and memory of test data/spectra across power cycles for rapid re-entry into testing state.
