Device for dilution of a gas to be analysed with a dilution gas

摘要

The device has a dilution gas supply for supplying dilution gas to a common pipe (6) in which gas-to-be-analyzed flows. The dilution gas supply extends in the form of a venturi nozzle (7) into the common pipe. A sample gas pipe (1) is thermally insulated from environment of dilution gas. The sample gas pipe discharges the gas-to-be-analyzed into the venturi nozzle. The sample gas pipe is surrounded by a coaxial external pipe. An end piece (1b) of the sample gas pipe is aligned coaxial to the venturi nozzle.
