ProUmid는 상대 습도뿐만 아니라 흡착 측정을 위한 최첨단 고성능 제품을 제조합니다.
Vapor Sorption Analyzer
Dynamic Vapor Sorption(DVS)은 사용자가 설정한 온도와 습도에서 Sample의 질량 변화를 측정하는 Gravimetric Method입니다.
Sample의 질량 변화는 주변 공기로부터 수분을 흡착하고 탈착하는 과정 속에서 나타나며 Sample의 특성에 따라 각각 다른 실험 결과를 받아 보실 수 있습니다.

* The full humidity range can only be achieved at a chamber temperature slightly above room temperature.
** Root mean square. The specified values assume that the system is installed in an environment suitable for the operation of microbalances.
The sample carousel with the dishes arranged in a circle is placed in the temperature and relative humidity controlled measurement chamber of the instrument. The atmosphere inside the chamber is continuously circulated, providing optimal air flow above the samples as well as uniform temperature and humidity at each point. All samples are weighed continuously. By turning and lowering of the carousel, one sample dish after the other is placed on the weighing pan. An internal reference eliminates all drift effects from the balance.
Operation of the SPS software and preparation of a measurement is very easy, straightforward and user-friendly. First some basic measurement parameters like the equilibrium condition are set and the temperature/humidity profile for the sorption/desorption cycle is defined. Finally, after taring, sample material is filled into the dishes and the initial sample weight is recorded. Once the start button has been pressed, the measurement runs completely automated. The results are continuously updated and displayed in tabular and graphical form. If necessary, the measurement settings can be adjusted during a running experiment at any time.
The sample dishes are filled outside the instrument by removing the whole sample tray. By this procedure, staining of the instrument during filling is avoided. In case of an accidentally contamination, due to plain surfaces of the instrument inside, the measurement chamber is cleaned easily.
