Selecting the Location

Online dewpoint measurement in still gas is much more demanding than

pressure or temperature measurement. A very tight installation is crucial:

not only pressure tight, but also vapor tight.

It is always best to connect the transmitter directly to the main SF

gas volume, not behind a sampling line. Avoid extension pipes,

T-pieces, and multi-connection points.
