ReactaVisc RV3 Reaction Vessel Viscometer

Compact, Real-Time Viscosity Monitoring for Reaction Vessels.

The Hydramotion ReactaVisc RV3 is a high-performance reaction vessel viscometer designed for continuous, real-time viscosity monitoring in small-scale or pilot reaction vessels. With its compact design and adjustable immersion depth via the HydraGland™ adapter, the RV3 offers flexible installation without the need for recalibration. Built from hygienic-grade stainless steel and rated to IP67, the device delivers reliable results even under harsh process conditions, with optional intrinsically safe versions available for hazardous zones.
