On August 12, 2021, Hermann Sewerin GmbH handed over four fully equipped gas warning device sets of the types EX-TEC® PM 400 and EX-TEC® PM 500 to the volunteer fire brigades of the Bad Neuenahr-Ahrweiler and the Altenahr community. The detailed instruction in the handling of the measurement technology was given by the sales engineer Mathias Blasius. We are pleased that with this donation we can contribute a small part to averting danger in the disaster areas.
