VisGuard 2 Extractive

Visibility Monitor

VisGuard 2 Extractive
  • Continuous monitoring of oil mist concentration using scattered light principle
  • Easy to service, high sensitivity, stability and accuracy
  • 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.
