Visible Spectrophotometer 722S, 340-1000 nm (CAT#: STEM-AL-8842-ZJF)

The 722S is a spectrophotometer intended for routine visible-light photometric analysis. It measures sample absorbance and transmittance by selecting wavelength-resolved ultraviolet or visible light. The optical system uses a C-T monochromator with a 1200 lines/mm diffraction grating. The stated wavelength coverage is 340-1000 nm. The source specifies transmittance, absorbance, stray-light, wavelength-accuracy, and repeatability performance. An RS232 interface provides serial data communication. The normalized record retains only technical information supported by the source. Overall, the instrument provides a compact visible-spectrum platform for routine photometry.
