Product Description

Geolux LX-80S is the innovative snow depth sensor that uses advanced 80 GHz radar technology to accurately measure the distance from the sensor down to the surface of the snow. The LX-80S offers superior performance compared to traditional ultrasound devices used for snow depth measurement.
Installing and maintaining the LX-80S is easy, and the device can cover a long detection distance of up to 15 meters.

The radar technology allows for non-invasive measurement from above the snow, ensuring that the snow’s structure is not disturbed in any way.
The LX-80S has many applications, including continuous monitoring of snowpack buildup and melting, making it essential for meteorological monitoring, hydrological planning, avalanche warning, and ski resorts.
The device provides accurate data on snow depth, which is crucial for many industries, especially those that depend on snow conditions.
Unlike traditional ultrasound devices that require temperature compensation due to their distance measurement being affected by air density, the LX-80S radar is not impacted by such environmental changes. Moreover, ultrasonic sensors are more susceptible to negative effects from snowfall or icicles, which can form close to the device. However, the LX-80S radar uses advanced signal processing algorithms for precipitation detection, and has a narrow radar beam of only 5°, which prevent such issues.
The low power consumption of the instrument, small form factor and a rugged enclosure make this instrument easy to setup and use.
