Sutron SatLink3 Lite Data Logger

Cost-effective solution to log and transmit data over geostationary environmental satellites.

The SUTRON SatLink3 Lite is the latest addition to the SatLink3 family. It offers a reliable and cost-effective solution for your environmental monitoring needs, optimized for simple applications. It allows measuring, processing, and logging data from smart sensors for up to 1 million readings without any overlap. Its built-in transmitter automatically selects the proper RF power, based on the antenna used, and delivers real-time data over NESDIS GOES 300 and 1200 bps as well as formats of other environmental satellites orbiting the globe.

LinkComm, the common operating software across the SatLink3 family, has built-in sensor templates, powerful dashboard, and diagnostics capabilities. Its intuitive user interface allows quick configurations, troubleshooting, and easy access to data. It is supported on PC, smartphones, and tablets (iOS, Android, Mac or Windows 7 and 10).
