The HZ‑7001B Rubber Mooney Viscometer is precision laboratory testing instrument for unvulcanized rubber. It measures rubber shear resistance torque under fixed temperature and rotor rotation condition to obtain Mooney viscosity value and Mooney scorch characteristic. This all‑in‑one device supports both Mooney viscosity test and Mooney scorch test. Adopts computer data acquisition & processing system, real‑time curve display, automatic data storage and report printing. It is essential quality‑control apparatus for rubber manufacturing, R&D laboratory and third‑party inspection organizations, complying with multiple global rubber‑test standards including ASTM D1646, ISO 289‑1.
