The 8920 Series Cellular and 8950 Series Satellite Tilt Loggers are ideal for smaller networks with a limited number of sensors, high-traffic areas (i.e. areas with radio interference), dense urban environments and areas with no line-of-sight between loggers. The 8930 Series Wi-Fi Tilt Loggers are ideal for underground mines, indoor environments and on structures with a Wi-Fi network readily available.

GeoNet Cellular,¹ Wi-Fi and Satellite Tilt Loggers can be added to sites with existing GeoNet 8800 Series and/or GeoNet 8900 Series Wireless Data Hosting Systems, allowing tilt readings to be taken in locations that are beyond the range of the existing network.

Seamless and secure cloud integration is achieved with GEOKON OpenAPI. The GEOKON OpenAPI portal is easy-to-use and allows users to activate loggers, change settings, configure sensor channels, and view current logger status. Industry leading data visualization software, or the no-cost GEOKON Agent Software, can be used with GEOKON OpenAPI for data viewing and reporting.

In addition, Solar Panels of various wattages are available for use with these Tilt Loggers.
