Advantages / Problems
- The nature of Dew Point is not determined directly that gives a lot of mistakes because the analyzer just does not know what has condensed.
- The technical capacity of the method is limited, so it has a big error.
+ The nature of Dew Point is determined more correctly than in classic method
- A fine sample filtration is needed (2 um unlike ordinary 7 um). Very sensitive to impurities.
- WDP is calculated which gives a big error.
+ Insensitive to impurities on the cooled surface.
+ Highly reliable.
+ Direct determination of the chemical nature of the condensate.
+ One module determines all kinds of Dew Point.
+ No influence of the cross-condensation.
+ Highly reliable and simple in operation.
+ Selective determination of water vapor content.
+ Competitive price in comparison to analogues.
- WDP is calculated which gives some error.
