    Advanced Technology

    Wherever hazards are expected, the EC 28 transmitter and GfG’s proven monitoring systems are the right choice for reliable surveillance. The ATEX-certified design, an integrated, Ex-proof buzzer, and bright alarm LEDs provide the highest safety in hazardous areas by including visual and audible alarms. The gas alarm not only alerts the person in the control room of hazards, but also the person on-site.

    Easy handling

    Smart sensor technology allows a user to install the transmitter or to replace a sensor within a few seconds – just plug the sensor into the transmitter. Adjustments are done directly at the transmitter using touch keys or with the remote control (one-person calibration).

    Remote Control RC2

    Ammonia and hydrogen are lighter than air. With the transmitter installed close to the ceiling, GfG can provide permanently connected cables with plugs for the remote control, which allow the user to do all adjustments without having to climb a ladder. In addition, one remote control can be used for several transmitters, which helps cut costs and increase efficiency.

    The remote control display is always identical to that of the transmitter, making inspection, service, and calibration considerably simple.

    The remote control reads the current gas concentration and can be used as an external display.

    Integrated Alarm – Saves Money on Ex-proof Alarm and Wiring!

    The EC 28 D model shows the current gas concentration on-site at the display of the transmitter and also at GfG’s GMA controller.

    The EC 28 DAprovides additional bright alarm LEDs and a buzzer – avoiding costs for a separate Ex-proof horn and an Ex-proof light. You also save money on wiring to connect the controller and alarm devices.

    In combination with GfG's flexible control units, the EC 28 provides various possibilities for reliable and cost-effective gas monitoring.

    Reliable Measurement, Increased Safety, Minimized Cost of Operation

    Accurate sensors and integrated temperature compensation provide the highest measurement accuracy. Low maintenance requirements and the long sensor life reduce your cost of ownership.
