A&D Weighing RV-10000 Vibro Rheometer

Description

The RV-10000 extends A&D’s tuning-fork vibration measurement technology from simple viscosity into rheometry — characterizing how a fluid’s apparent viscosity changes with the amplitude of vibration applied to it, which is what makes it useful on non-Newtonian fluids (shear-thinning or shear-thickening samples) as well as straightforward Newtonian ones that a standard viscometer already handles well.

Amplitude is adjustable from 0.07 to 1.2mm, letting a single instrument probe a fluid’s behavior across a range of effective shear conditions rather than reporting one fixed-condition number. Accuracy is stated at ±3% (1-1,000 mPa·s) when amplitude is set to 0.4mm, with repeatability of ±1% of the measured value. Minimum sample size is 10ml, setup is self-calibrating, and like the SV series it uses the tuning-fork vibro method at a 30Hz natural frequency — fast measurements with minimal mechanical shear on the sample, which matters when the fluid’s shear-dependent behavior is exactly what’s being characterized.

**Frequently asked questions**

**What’s the difference between a rheometer and a viscometer here?** A viscometer (like the SV-10 or SV-100) reports a single viscosity value under fixed conditions. The RV-10000’s adjustable amplitude lets it probe how viscosity changes with applied shear/amplitude, which is what’s needed to properly characterize non-Newtonian fluids.

**Do I need to calibrate it before each use?** The RV-10000 is self-calibrating, which keeps setup fast between samples.

**What’s the difference between the RV-10000 and the RV-10000A?** Both share the same measurement range, accuracy, and vibro rheometer technology; the RV-10000A adds a dedicated digital controller for more automated data output and logging. Choose the RV-10000A if automated data capture is a priority.
