GSM data collection, process control & wireless remote control


The Hastel GCOM-3D provides a reliable, low cost solution for a wide range of control, monitoring, logging and alarm messaging applications.

This quad band GSM device can monitor, log, alarm and control simultaneously and may be configured by the user with an easy to use windows program and cable.

Already successfully integrated into client applications, the GCOM-3D offers a cost-effective solution to OEMs, instrumentation, sensor and meter companies, MCC manufacturers, industry and factories. Through our in-house application engineering and web hosting services, we can develop custom telemetry and data management solutions.
