VisGuard 2 In-situ

Visibility Monitor

VisGuard 2 In-situ
  • Easy to service, high sensitivity, stability and accuracy
  • Easy zero-point checking, even when visibility is poor
  • A special sample flow concept entirely eliminates the danger of flow cell contamination
The VisGuard measures the scattered light intensity of a sample drawn into the instrument. Filtered purge air is fed through the flow cell, thus enveloping the sample in a protective shroud of clean air. This effectively keeps the optics clean. Installations are either in the tunnel cavity/niches (in-situ) respectively using extractive sampling away from the cavity. An optional sample heater eliminates the influence of any mist effects.
