RheoVADR® Rheometer

The Fann RheoVADR® Variable Automated Digital Rheometer gives new meaning to the term “stand-alone.”

No Computer Needed

An operator can record test data without connecting the instrument to a computer or network. Speed, viscosity, dial reading, and temperature are recorded for each test. Additional test data can be recorded on a USB flash drive. Plug a flash drive into the USB port, select a data recording speed, and touch the “Record” button or select a pre-programmed API tests. Data is captured in a standard CSV file that can be read by Microsoft Excel and other spreadsheet programs. Data recordings are limited by the capacity of the flash drive.

Lab or Field

A Universal Power Adapter allows the RheoVADR® Rheometer to be used in the lab or in the field.
