Transmitter EC28

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.
