摘要 |
The present invention pertains to a device for cooling testing tubes during sampling by evaporating a liquid. The cooling device causes a controlled cooling effect that is practically independent of the state of the ambient air during the sampling and is easy to handle. After flowing through the testing tube (2), the gas to be investigated flows through a layer of filler (7) that surrounds the testing tube (2) and is impregnated with a liquid.
