Technical Data Sheet

 I.Main features

 1. The new optical system design, the instrument host has excellent optical properties and photometric performance, low noise and

  stray light,high photometric accuracy and stability and reliability.

 2. Unique deuterium and tungsten lamps installed, the source was automatically switched and find the best position in the design and

  working methods, allowing users to operate the instrument and maintenance of replaceable light source it is more convenient, accurate

  and secure.

 3. Excellent software design and preparation, the instrument has a strong spectral data processing functions: scanning measurement

 spectrum, multi-wavelength (1 ~ 3λ) determination of kinetics, 1 to 3 times  curve fitting,

  1-4 derivative spectrum access display print spectra and analyze data.

 4. The large screen Chinese window displays, has a good interactive interface.
