ASTM D2983 viscosity tests typically involve a lot of hands-on time to prepare and run the tests. The new, fully automated thermoelectric sample conditioner (TESC) system for ASTM D2983 is designed to lessen the hands-on time needed while improving test precision.
Incorporating a Brookfield® DV2T digital viscometer and thermoelectrically controlled sample chamber, the TESC system automates the entire conditioning and testing process, including preheating, room temperature stabilization, cooling of the sample to test temperature, and testing the final viscosity of the conditioned sample.
Integrating all conditioning and testing processes in a self-contained unit eliminates the temperature fluctuation and result variability associated with sample transfer and disruption.
The system uses integrated thermoelectric heating and cooling to control temperature from -40 to +90°C and provides temperature accuracy greater than ± 0.1 °C. When used with the Brookfield® DV2T, thermal test history and final viscosity measurements are recorded at multiple spindle speeds and accessible for export into various software programs upon test completion.
A footprint one-half to one-fourth that of even the smallest alternative D2983 sample conditioning unit allows labs to purchase and operate multiple of these systems without the requirement of additional bench-top space. Using multiple systems allows uninterrupted testing during maintenance of individual units and offers the flexibility of having each unit programmed to a different test temperature.
