The TROLL Net Hub is a networking device that connects up to four or eight instruments into your telemetry or SCADA/PLC system. The hub is ideal for long-term remote site monitoring and process control, including applications like aquifer characterization and nested well monitoring.

You can customize the system by linking a variety of In-Situ sensors, and even connect multiple hubs to network up to 16 devices. The Net Hub supports twist-lock or stripped-and-tinned cables.
