TA Instruments - VTI-SA+
Designed for high performance sorption analysis of materials under controlled conditions of temperature and humidity.
Designed for high performance sorption analysis of materials under controlled conditions of temperature and humidity.
The VTI-SA+ Vapor Sorption Analyzer is a continuous vapor flow sorption instrument for obtaining precision water and organic vapor isotherms at temperatures ranging from 5°C to 150°C at ambient pressure. The VTI-SA+. Analyzer embodies the features of VTI’s original SGA design with almost two decades of field-proven performance: the isothermal aluminum block construction, the three isolated thermal zones and chilled-mirror dew point analyzer for primary humidity measurements… all to provide excellent temperature and RH stability.
