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 (optional). The gas alarm not only alerts the person in the control room of hazards, but also the person on-site.

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 RC2 remote control (one-person calibration).

The remote control display is always identical to that of the transmitter, making inspection, service, and calibration considerably simple. In addition, one remote control can be used for several transmitters, which helps cut costs and increase efficiency.
