TransFlexion Probe for Industrial Applications

Main Features

  • Sapphire optics
  • On-line transmission spectroscopy at long distance in wide range of liquids (from transparent to poorly transparent)
  • High throughput in any part of UV –VIS or VIS – NIR spectra
  • Flexible and robust for industrial applications in harsh environment
  • Compatible with all spectrometers

FlexiSpec®product line includes the latest generation of Transflexion Dual Pass fiber optic probes to be used with any spectrometer or photometer  in any part of UV –VIS or VIS – NIR spectra.

Hastelloy C22 schaft is suitable for industrial applications and for work in harsh environment. Sapphire windows  and a number of removable heads with variable optical path length allow to use TransFlexion probe  in wide range of liquids and concentrations. Upon request, more than one removable head can be included per order. Possible slit sizes range from 0.5 – 20mm.
