Provides an accurate reading of surface conditions, including water, ice and snow amounts and a high resolution value for grip level. Pole mounted roadside set-up eliminates the disruption caused by slot-cutting, making installation and maintenance relatively easy. Can be used as a stand alone system on bridge decks, in remote locations or as part of an existing ROSA weather station.

This thermally passive multi-variable sensor measures road / runway surface and subsurface temperatures, as well as water layer thickness, black ice and chemical levels.

A non-contact multi-variable sensor measuring overhead wire temperature and state (water / ice layer thickness, presence of snow etc).

This thermally passive multi-variable sensor measures conductor rail temperatures and state (e.g. water / ice layer thickness, presence of snow).

A sensor with shallower physical dimensions to enable installation on bridge decks.
