britainBiral Corporation is the world's leading manufacturer of the Forward Scattering Visibility Weather Phenomenon Instrument (HSS). The HSS visibility instrument was the first infrared instrument in the world in 1980 and has been developed and used for 40 years.

It has excellent measurement angles and geometric structures, high accuracy and reliability, and can maintain no leakage in harsh environments, playing an important role in various fields.

After years of research and experimentation, Biral has launched the SWS series, in which the SWS-100 visibility range can be selected up to 75 kilometers (* if users require a higher range, 10m can be customized)～90km）.SWS-100 sensor can be used for road and general weather measurement, and can identifyDrizzle, rain, snow, fog, hazeTypes of visual impairment and weather phenomena.SWS-100 can select digital and analog outputs to data collectors and other systems. The SWS series has relay contacts that output programmable fog and rainfall information. For example, when visibility drops to 100 meters, one relay is used to set the "deceleration" information, and when it rains, another relay is used to output the "slippery danger" information.

The sensor is reliable in quality, cost-effective, with remote monitoring and self checking information, minimal maintenance, and easy to useThe SWS-100 sensor can save a lot of costs from installation to operation, and is lightweight and portable, making it easy to install on pillars. The SWS series sensors use the same technology as the HSS sensors. The SWS series is an economical visibility and current weather phenomenon meter designed for use on highways, as well as in meteorological and wind energy applications.

The equipment is made of high-quality structural materials and coated with aluminum powder coatingSWS current weather phenomenon meter is suitable for most environmental conditions (if it is a corrosive environment, such as marine environment, or other polluted environment, we recommend using our HSS anti-corrosion sensor), with digital and analog output signals, and relays that can control other external devices.

The SWS series current weather phenomenon meter is based on proven HSS technology. Our high specification HSS range visibility and current weather phenomenon meter has been used worldwide for over 20 years.
