Different versions
As the sampling system is adapted to individual measurement needs, a large number of di f-
ferent versions are required. Which version is used depends primarily on the following:
The sampling type, i.e. single or multiple sampling.
The maximum line length from the sampling point to the measuring instrument.
The following table provides an overview of the different versions available.
An overview of the measuring points can be found in the corresponding drawings.
