Muli-Parameter Online Photometers Probe Overview

All i::scan probes are compact multi-wavelength photometer probes, capable of high quality online measurements of light absorption with  either directly submersed in liquid media (in-situ) or in by-pass via flow cell setup. The probe can be operated also outside of the medium using a multifunctional slide. i::scan probes with a path-length of 35mm also have an additional 90 degree detector for scattered light measurements including suitable light sources. This allows measurements of turbidity according to ISO 7027 and similar to EPA 180.1

For absorption measurement the sensor works as a multi-wavelength photometer with narrow band light sources. The wavelengths have been carefully selected to best fit the intended applications. For organic parameters multiple wavelengths in the UV-A/UV-B and UV-C range are used. For colour, solids and turbidity measurements light sources in the visible and near infrared range are used.

Muli-Parameter Online Photometers Probe Features
