ETM9120-422 is an intelligent GPRS terminal with a powerful microprocessor designed for demanding industrial applications. ETM9120 is suitable for monitoring and controling installations where no fixed communication connection is available. The low power consumption of less than 1 milliwatt makes ETM9120 suitable for battery operation with long service life.

Typical applications include data acquisition from electricity-and water meters, pump monitoring, level measuring in lakes and ponds and temperature measuring in cooling facilities and server rooms.

ETM9120 is equipped with 7 inputs / outputs and can also provide power supply to the sensors with stabilized 5V, 16V or supply voltage.

ETM9120 combined with EWO (ETM Web Office) is a complete solution for data collection with a Web-based interface for easy access to collected readings.
