​​​​Dryer performance is critical when moisture sensitive materials, such as PET resin and nylon, are dried prior to molding. Dew point measurement can be used to monitor a dryer’s performance or conditions in the hopper, assuring that the drying process remains within specification.

Vaisala has a range of stable and reliable dew point transmitters both for OEM configurations as well as for end users.

For those who prefer a direct measurement of humidity or dew point temperature within the hopper, which can correlate to moisture content of the material in the hopper, Vaisala offers a portable sampling system DSS70A to be used with a hand-held meter DM70.
