Rheometer RC20-CPS

for quality control, process engineering and product design

 

The Cone-Plate Rheometer RC20-CPS is a rotational viscometer for quality control, process engineering and product design.

A high developed dynamic measuring drive system enables rotational tests with Controlled Shear Stress (CSS) and Controlled Shear Rate (CSR).

 

Special Features

microprocessor-controlled measuring device for mains power operation

torque overload protection

user-friendly, dust proof keyboard for manual operation

integrated alphanumeric display (4-lined) showing optional 4 current parameters (dynamic viscosity, shear rate, shear stress, rotational speed, torque or temperature)

RAM data buffering, storage of data (incl. data and measuring-count) for maximum 10 experiments with up to 4,800 measuring values

cone/plate and plate/plate measuring systems (DIN 53018, see table)

sample temperation by liquid circulator, Peltier heating, or electrical heating

PC control including data analysis (software package RHEO2000)
