Dynamic Vapor Sorption Analyzer - DVS Adventure

Water Vapor Sorption Analyzer - DVS Adventure

The DVS Adventure is an advanced water vapor sorption analyzer, built to measure sorption and desorption isotherms across a wide humidity and temperature range. It excels in temperature stability and humidity performance, delivering critical insights into how samples interact with water vapor—vital for developing new materials and processes.

Humidity Performance and Stability

• High accuracy: Top humidity precision in its class; generated RH typically varies only ± 0.1% RH from the target.

True0™ RH Technology

The gravimetric sorption analyzers from Surface Measurement System uniquely offer True0™ RH.

• Extreme precision: Reaches water partial pressures as low as 0.0% RH.
• Critical applications: Essential for hydrates and compounds that dry below 1% RH, plus sorption/desorption studies at very low humidity.

Advanced Temperature Control

DVS Adventure delivers next-generation temperature control with exceptional stability throughout the instrument.

• Operating range: 5 to 85 °C.
• Precision: Typical stability at 25 °C of ± 0.02 °C.
• Avoids common issues: Reduces condensation risk in varying temperature zones, ensuring more accurate, stable humidity distribution.
