Visibility solutions with precise measurements
Hans Buch supplies visibility sensors and weather sensors from Biral for applications where precise measurements in challenging weather conditions are essential. The solutions are used in areas including road transport, aviation and marine environments, where real-time data can be crucial for safety, traffic flow and operations.

Visibility measurement for critical infrastructure and safe operations
Precise visibility measurement is essential in environments where weather conditions directly affect safety and operations. Hans Buch supplies professional visibility sensors from Biral for airports, road transport, marine installations and other critical infrastructure, where reliable measurements support fast, safe decisions.
The sensors provide real-time data on visibility and atmospheric conditions, enabling operators and operational staff to respond proactively to fog, precipitation and other challenging weather conditions.
Visibility sensors and weather sensors in one solution
In addition to precise visibility measurement, the solutions also include weather sensors that record parameters such as surface temperature and weather conditions. This combination provides a more complete picture of current conditions and supports better decisions in traffic management, winter road maintenance and operations.
Combining multiple measurement parameters in a single system makes monitoring both simpler and more efficient.

Sensors for different distances and applications
Hans Buch offers several types of visibility sensors from Biral, covering different measurement needs.
- VPF-710 – measurement range from 10 metres to 100 kilometres
- SWS-050 – suitable for short and medium distances
- SWS-100 – developed for longer measurement distances and marine environments
The sensors are used in airports, on motorways, in ports, offshore installations, wind farms and other environments where precise visibility measurement is essential.
Robust sensors with real-time data
Biral sensors are designed for continuous operation in demanding weather conditions. Their robust construction and fast response time ensure stable measurements around the clock, even in rain, fog, snow and high humidity.
Real-time data can be integrated with existing monitoring and control systems, allowing the information to be used directly in day-to-day operations.
