Biral is the manufacturer of the VPF and SWS Visibility and Present Weather sensors which are used worldwide.
The renowned VPF range of visibility and present weather sensors are the most accurate and durable on the market (with a proven track record of over 20 years) and are a must for many critical applications.
However, for applications not requiring such extreme levels of robustness and accuracy we have now introduced the new SWS low cost range of present weather sensors. The SWS sensors are less expensive than competitive sensors of a comparable quality. Please see all models below.
