Bohlin Instruments Gemini 200 Rheological Characterization System. Research grade rheometer optimized for both strain controlled and stress controlled operation. Proven Inductive motor technology powerful yet low inertia motor design enables adjustment of position or speed more rapidly than conventional motors with permanent magnets and optimum dynamic response necessary to perform transient and dynamic test protocols with excellent low torque response. Exceptional position and speed sensing. Torque Range: 0.05µNm to 200mNm in controlled stress and rate viscometry. 0.05µNm to 200mNm in controlled stress and strain oscillation. 110-220V, 50/60 Hz, 5/2A, CE. Does not include PC or software.
