Spectrophotometer with Wavelength Accuracy (Si02 Mirror)


Key Features

  • Large LCD screen (128*64 Dots) with saving standard curve function
  • Adopted high-class grating with wholly hermetic light path design, to ensure the instrument has the super low stray light
  • With Si02 coating optical mirror, reducing the pollution from outside fully
  • Wavelength calibration, wavelength setting, change lamp source and dark current calibration automatically
