DVS Intrinsic Plus
Description
Surface Measurement Systems
The DVS Intrinsic Plus is the smallest automated DVS for complex water sorption challenges from Surface Measurement Systems. The Intrinsic Plus was designed to meet the needs of the small to mid-sized laboratories and plants. It combines ease of use with a low capital investment and maintenance burden.
The system incorporates the SMS UltrabalanceTM, and industry leading electronics. The user interface combined with the step-by-step software wizards yield high performance with minimal operator training. The unit’s small footprint makes optimal use of limited bench top space.
