SD500 Highway Weather Station

The SD500 highway weather station consists of six elements SW600, visibility sensor SW106, road condition sensor SW107, collector and lightning rod. It can simultaneously observe ambient temperature, ambient humidity, wind speed, wind direction, air pressure, rainfall, rainfall intensity, visibility, snow/water accumulation/icing thickness and wet slip coefficient. It has the characteristics of convenient installation, stable performance, high detection accuracy and no need to be on duty.


- Adopting SW series micro-meteorological sensors independently developed by the company, the sensor has low power consumption and can operate reliably under severe conditions;
- Non-contact road surface sensor, using remote sensing technology to avoid damage to the road;

- Maintenance-free, stable performance, compact structure and easy installation;

- high measurement accuracy;

- Remote control can be issued to support remote upgrades.
