Rheology is the study of flow and deformation of materials. Deformation and flow are referred to as strain or strain rate, respectively, and indicate the distance over which a body moves under the influence of an external force, or stress. For this reason, rheology is also considered to be the study of stress-strain relationships in materials.

A rheometer is a precision instrument that contains the material of interest in a geometric configuration, controls the environment around it, and applies and measures wide ranges of stress, strain, and strain rate.

TA Instruments’ Discovery Hybrid Rheometer is the world’s most versatile platform for rheological measurements. The ARES-G2 is the most advanced rotational rheometer for research and material development. Both platforms have a full range of environmental systems and measurement accessories, powered by SmartSwap™ technology for fast exchange and automatic configuration.
