The VISIC620 determines the standard visual range on roads, sea routes, or in weather observation stations or measures the visibility (as k-value or in mg/m³) in tunnels. An automated self-test measures and compensates for possible front screen contamination. Furthermore, it offers excellent recognition of objects such as leaves or plants in the optical path. Therefore, the VISIC620 can measure fog reliably.
The maintenance interval of five years (except cleaning), the rugged stainless-steel housing and the possibility of power supply via solar cells or battery make the VISIC620 a real outdoor product, even in salty air.
