Overview
Double Beam UV/Visible Spectrophotometer LMUD-A205 is a high-class grating instrument with hermetic light to ensure that the instrument has extremely low stray light. It has a self-check function to check the wavelength and photometry accuracy. It has a SiO2 protection coating to block the outside pollutants. There are 65000 true colors and support U disk for data saving.
