ATS RheoSystems has unveiled version 6.0 of its RheoExplorer software package for viscometry applications. Designed to run under 32-bit Windows 2000 or XP, the updated program provides speed, flexibility and operating stability for configuring and using rheology hardware from Reologica Instruments. Via an Ethernet connection, it supplies high-speed data transfer and control of a rheometer. It also is compatible with the Linux operating system within the rheometer, enabling improved performance compared with previous versions. The software features modules for steady shear viscometry, yield stress determination, oscillation under strain and stress control, and creep and recovery. It enables model fitting, relaxation spectra calculation and interconversion of rheological data.
