The transmission of energy from the base station () to the mobile gas-measuring device () is carried out reliably and with a high level of safety, even in the presence of explosive gases with a gas-measuring system () including a mobile gas-measuring device () with a battery unit () and with at least one sensor () for detecting a gas concentration. A base station () for the mobile gas-measuring device () is provided as well as an interface () for transmitting electric energy from the base station () to the battery unit () of the mobile gas-measuring device (). The interface () for transmitting electric energy from the base station () to the battery unit () of the mobile gas-measuring device () is designed such that the electric energy is transmitted at least partly in a wireless manner.

Rechargeable gas-measuring system

A test adapter for the saturated vapor calibration of gas-measuring devices. The test adapter () has, in an adapter housing (), a peripheral edge () for receiving a gas-measuring device and has a depression () for receiving the sample liquid in the area of the gas-sensitive surface of the gas-measuring device.

Test adapter for a gas-measuring device

Safety clothing () for persons in dangerous situations is provided including at least one device () for generating light and/or at least one device for generating sound and/or at least one mechanical device for generating a warning stimulus, which is perceptible by the person, an interface () for generating data or signals with a gas-measuring device () and a power supply device () for supplying the at least one device () and/or the interface with power. The features are in functional connection with one another, for optically and/or acoustically and/or mechanically warning the person when at least one limit value of a harmful gas is exceeded or in case of at least one implausible measured value of the air detected by the gas-measuring device ().
