The Model 5000 analyzer measures moisture on-line by monitoring the vibrational frequency change of a hygroscopically sensitized quartz crystal that is exposed alternately to wet sample and dry reference gas for 30 second periods. The reference gas is sample gas passed through a molecular sieve dryer to remove virtually all its moisture content.
