Gas Detection System

In a gas measuring system (1) comprising a mobile gas meter (2) having a battery unit (6) and at least one sensor (8, 9, 10, 11) for detecting a gas concentration, a base station (3) for the mobile gas meter (2) , an interface (7) for transfer of electrical energy from the base station (3) to the battery unit (6) of the mobile gas meter (2), to the power transmission from the base station (3) to the mobile gas meter (2) and with reliable a high security - can be carried out - even if the presence of explosive gases. This object is achieved in that the interface (7) for transfer of electrical energy from the base station (3) to the battery unit (6) of the mobile gas-measuring device (2) is designed in such a way that the electrical energy is at least partially transmitted wirelessly.
