New Product Alert – VICONOX-0 Visibility Monitor

Thu 24 Mar 2016

Tunnel Sensors launch VICONOX-0, a visibility monitor designed to replace the existing VIPA solution.

By replacing VIPA with a visibility only VICONOX solution, Tunnel Sensor customers will benefit from a number of design enhancements that help make VICONOX simpler to install and better suited to the harsh operating environment often found in tunnels.



Like all Tunnel Sensors products, the VICONOX-0 has been designed to withstand extreme weather conditions. The complete electronic system is contained within a water-proof, heated housing of 316 Stainless Steel and has an operating temperature range from -30oC – +70oC which ensures stable readings across all prevailing ambient temperature conditions. Orders for VICONOX-0

are already being taken and are available within our standard lead times.

Tunnel sensors will continue to support existing VIPA devices throughout their 24 month warranty period.

For further information about VICONOX-0 and all other products within the Tunnel Sensors range, please contact our sales team.
