| Summary: | An adapter (
1
) and electrochemical gas sensor (
2
) is provided with an electrochemical gas sensor housing (
14
) accommodating an electrolyte (
13
), with at least one measuring electrode (
12
) arranged therein and with a membrane (
11
), which screens the measuring electrode (
12
) from a measured gas and is permeable to the measured gas. The measuring sensitivity of an electrochemical gas sensor is increased by the adapter (
1
) having a gas-impermeable surface (
15
) extending in parallel to and at a spaced location from the membrane (
11
). The adapter (
1
) and the membrane (
11
) form a flow gap (
10
) for the measured gas delivered by a pump. The adapter (
1
) may be plugged onto the electrochemical sensor (
2
) at its outer edge (
1
a
). The measured gas enters through a central opening (
17
) , expands in the flow gap (
10
) radially to the outside and leaves same via the ring-shaped gap (
16
). |
