r-condition non-invasive road monitoring sensor - a single device, without the need for any additional hardware (it could also be used with other sensors and mounted onto a complete road weather information system). It measures the temperature of road surface and detects the appearance of water, snow and ice formation, as well as measures the water film thickness and calculates the road friction coefficient.
RainBal precipitation gauge
Weighing Principle Precipitation Gauge is an advanced meteorological device that uses weighing to measure precipitation, providing more reliable results. It has a simple design and robust materials, thus ensuring low power consumption and low operational costs. Influence of wind, vibration, evaporation and temperature fluctuations are eliminated, achieving the highest accuracy of measurements.
