Visible Spectrophotometer 722SP, 325-1000 nm (CAT#: STEM-AL-8843-ZJF)

The 722SP is a spectrophotometer intended for visible-light absorbance and transmittance measurement. It measures sample absorbance and transmittance by selecting wavelength-resolved ultraviolet or visible light. The optical system uses a C-T monochromator with a sealed grating. The stated wavelength coverage is 325-1000 nm. The source specifies wavelength accuracy, repeatability, stray light, and photometric performance. An RS232 interface supports serial data transfer to external equipment. The normalized record retains only technical information supported by the source. Overall, the instrument provides a sealed-grating visible photometry platform.
