Double Beam UV-VIS Spectrophotometer
Double Beam UV-VIS Spectrophotometer
Product Code : JS-2700
Product Description

Features

The True Double Beam UV-VIS spectrophotometer with advance circuit measurement and control system , make the instrument with hig realiability and low noise. Excellent software design and procedure, make instruments have stronger spectral data processing function;Automatically scam measures spectra, multi wavelength (I -3 Lamda) determination, kinetic determination, 1-3 curve fitting, 1-4 derivate spectra, access, display print spectra and analyze data. Powerful window based software platform user-friendly, powerful, easy to store or output. Unique installation of deuterium & Tungsten lamp, the design and working way of automatic light switch and finding the best location, allowing users to operate the instruments and maintain or replace light source in a more coinveninent, correct and safer way.
