DVS Intrinsic

DVS Intrinsic

The DVS Intrinsic is the latest dynamic gravimetric water sorption analyser from Surface Measurement Systems. The Intrinsic was specifically 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. Via DVS-IntrinsiLinkTM, one PC can operate up to 5 DVS Intrinsic units at the same time.
