DVS Model The Model DVS-SA VTI vapor sorption analyzer operates with a continuous flow of accurate adsorption isotherms of water vapor and the vapors of organic solvents at temperatures between 5 ° C and 60 ° C under normal pressure to obtain (DVS - dynamic vapor sorption).
The VTI-SA analyzer embodies the features of the original VTI-SGA's design.
The isothermal aluminum block construction, the three isolated areas, and the thermal dew-level Hygrometer for the determination of moisture to ensure an excellent temperature and humidity stability.
