VISGUARD OMD

Oil Mist Detector

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. Oil dust in the sample can be detected early to help preventing from further incidents.

• Continuous monitoring of oil mist concentration using scattered light principle
• Fully complying with the latest IMO code of practice for atmospheric oil mist detectors
• Easy to service, high sensitivity, stability and accuracy
