Sampling selector switch
The Sampling switch can change between two and seven sampling lines in, and one line out to analyzer or gas cooler.
When we made the measurement, they can switch between
2 a.m. to 7 p.m. at a sampling analyzer / gas cooler or similar switch
For the calibration, there are two gas connections once for zero gas, and once for the sample gas.
There is also the possibility of cascading several modules.
