Overview of Sentry™ Visibility Sensor (PDF)
This document demonstrates the Sentry™ sensor’s performance in key areas including a comparison with other visibility sensors, performance in challenging conditions like extreme weather conditions, accuracy & precision, and long-term reliability in the field (MTBF).

Visibility Sensing Techniques (PDF)
This paper briefly examines the advantages & disadvantages of forward and back scatter techniques for measuring atmospheric visibility.

Visibility Sensor Accuracy (PDF)
This paper proposes a reasonable level of accuracy to be expected from electro-optical visibility sensors by comparing manufacturers’ claims versus real-world testing by meteorological organizations, and promotes the need for standardization in visibility testing and reporting.

Performance of the Sentry™ Visibility Sensor in Obstructions by Blowing Dust & Sand (PDF)
This document demonstrates that obstructions to visibility from windblown dust and sand fall well into the detection capabilities of the Sentry™.
