Double Beam UV Spectrophotometer 190-1100nm

Order Id: ST-UV-1901PCS
Categories: Spectrum  Spectrophotometer 

Instrument Function:

l   Photometric measurements: simultaneous measurements at a wavelength of 1~ 6 of transmittance and absorbance.

l   Spectral measurement: in the wavelength range for transmission, absorbance and energy spectrum scanning, and various data processing such as peak and valley detection, derivative computation, spectrogram operation, etc.

l   Quantitative measurement: single wavelength, dual wavelength, three wavelength and multi-wavelength measurement. 1 ~ 9 work curve (1 ~ 4 times) regression.

l   Dynamic measurement: time scanning of transmittance and absorbency in any set of wavelengths and may carry on various data operations.

l   Data output: can undertake data file and parameter file access; the measured results are output in standard data file format.
