Software specifications


Now all Labomed, Inc. split and double beam spectrophotometers with our newly developed
software called UV-Win 6.0 can be used with Windows XP, Windows 7 and Windows 8. It is capable of testing more applications with its RS-232 and USB connections, and supports the data export of measured results to the PC and then flash drive, when additional data storage is required. One of the new features is that it provides 3-D graphing of the spectral results.

Monoprocessor Built-in Application:

  • Photometric Measurement: Measuring transmittance or absorbance at the current wavelength together with K factor calculations.
  • Spectrum Scan: Carrying out scanning of transmittance or absorbance on the selected wavelength range together with peak-pick module.
  • Quantitative Determination: Regression of standard curves and direct determination concentration of samples.

PC Windows Application Software (RS-232 and USB Interface) to link Spectro to computer and printer:
