Passive Road Surface Temperature Sensor WST1

Categories: ,

Surface temperature sensor for runway and highway-temperatures

The surface temperature sensor measures runway and highway-temperatures highly precise, both on asphalt and concrete. The Surface temperature sensor WST1 works in conjunction with the intelligent active road sensor ARS31Pro and any WS weather station (except the Lufft WS100 precipitation sensor) of the Lufft UMB-Technology.
