For toxic gases, oxygen and hydrogen

Superior technology
Wherever gas hazards are to be found, the EC28 provides the best solution for safe monitoring. ATEX-certified design, built-in EX-certified horn and bright LED lights allow safe operation. The gas alarm is transmitted to the central control panel, simultaneously warning the control room and the worker in the danger area.

Smart sensor technology
Installation and sensor exchange are quick and easy using pre-calibrated smart, plug-in sensors. One-man calibration/ adjustment is possible directly at the transmitter, without opening the housing.

Remote control (option)
Some flammable gases are lighter than air (e.g. methane). If a transmitter is installed close to the ceiling, it can be connected by a fixed installed cable with a plug connection to the remote control. Thus, all adjustments can be made comfortably from floor level. With one remote control device, an unlimited number of transmitters can be controlled in this way.

Using transmitters without display, the remote control shows the current values on its’ own display. The display of the remote control mimics the transmitter display exactly. Inspection, maintenance and adjustment are therefore greatly simplified. Using the remote control inspection, service and calibration can be performed easily by one person.
