A&D Weighing RV-10000A Vibro Rheometer with Digital Controller

Description

The RV-10000A carries the same tuning-fork vibro rheometer technology as the RV-10000 — adjustable vibration amplitude from 0.07 to 1.2mm to characterize how a fluid’s apparent viscosity shifts with applied shear, useful for non-Newtonian as well as Newtonian fluids — paired with a dedicated digital controller for more structured data capture and output.

Accuracy and repeatability match the base RV-10000: ±3% (1-1,000 mPa·s) at 0.4mm amplitude, ±1% repeatability of the measured value, and a 10ml minimum sample. The RV-10000A is self-calibrating and uses the same low-shear, fast tuning-fork measurement principle (30Hz natural frequency) as the rest of A&D’s vibro viscometer line. The added controller unit is the main practical difference from the base RV-10000, aimed at labs that want more automated logging built into the rheometer setup itself rather than relying solely on a connected PC.

**Frequently asked questions**

**Should I get the RV-10000 or the RV-10000A?** They share identical measurement specs. Choose the RV-10000A if a dedicated digital controller for automated data output and logging is important to your workflow; choose the base RV-10000 for a simpler standalone setup.

**Can it measure non-Newtonian fluids?** Yes — the adjustable amplitude (0.07-1.2mm) lets you observe how a sample’s apparent viscosity changes with applied shear, which is the key measurement for characterizing shear-thinning or shear-thickening (non-Newtonian) behavior.

**What’s the minimum sample size?** 10ml.
