Advanced Rheometer: AMETEK Brookfield Launches the RSX Touch Screen Rheometer for Controlled Rate/Stress Measurements

Monday, March 14, 2022

MIDDLEBOROUGH, MA – AMETEK Brookfield, part of AMETEK's Instrumentation & Specialty Controls Division, is excited to announce the launch of its new RSX Rheometer. The RSX is an advanced rheometer instrument with a touch screen for controlled shear rate (rpm) and controlled shear stress (torque) modes—for sophisticated rheological analysis. The RSX series of touch screen rheometers represent the best that AMETEK Brookfield has to offer. With automatic data collection and analysis using the optional Rheo3000 software, RSX Rheometers offer greater flexibility and more features than other high-end rheometers in their class—at a fraction of the cost.

“The RSX Rheometer is a rugged instrument ideal for quality control (QC) purposes,” said Kai Johnstad, AMETEK Brookfield’s Manager of Global Product Marketing. “This instrument has the ability to perform a wide range of complex rheological analyses on products from industries including food and beverage, pharmaceutical, paints and coatings, and chemical production.”

The rugged design of the RSX Rheometer permits use on the production floor. Increased torque motor enables testing and measurement on the toughest of samples. The instrument quantifies meaningful properties like stiffness, wobbliness, sloppiness, consistency, and texture. The large, 7-inch user-friendly touch screen and graphical display provide stand-alone simplicity for operation by QC users. Controlled shear stress/shear rate operation makes it easy to study material behavior from initial yield to flow curve response. Rapid temperature control of plate with Peltier or fluid heated options provide quick profiling of viscosity vs. temperature. The RSX is available in cone plate (CPS), coaxial cylinder (CC), and soft solids tester (SST) configuration. With optional Rheo3000 software, the RSX can be controlled via PC for data acquisition and analysis of multiple test files.

AMETEK Brookfield has been the world standard in viscosity measurement for over 85 years. AMETEK Brookfield's expanding portfolio includes texture, toxic gas, moisture, and powder flow analysis instruments.
