HSS Visibility and Present Weather Sensors

HSS Home Page

Biral HSS Visibility and Present Weather Sensors provide the highest levels of accuracy available on the market. They were the first optical sensors to combine an infra-red light source with forward scattering technology to give the best performance possible and have been leading the way in optical visibility measurements for over 20 years.

There are three models available, VF-500, VPF-710 and VPF-730 (see links to these models below) and they are used around the world in a variety of applications.

Application examples (these links open in a new window):

• airport visibility and RVR (using VPF-710 / 730) (more - htm)
• windfarms - landbased and offshore (using VF-500 /VPF-710)  (more - pdf)
• lighthouse and offshore platform fog warnings (using VF-500) (more - pdf)
• offshore weather stations (using VPF-710) (more - htm)
• bridges (using VF-500) (Severn Bridges article - pdf)
• highway visibility using all 3 models (more -  pdf)
• climate and atmospheric research (more - htm)
• other instrument calibration (more - htm)
