The EC 28 DA provides 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.Accurate sensors and integrated temperature compensation provide the highest measurement accuracy. Low maintenance requirements and the long sensor life reduce your cost of ownership.
