Introduction

The RheoVADR

®

Variable Automated Digital Rheometer is the latest addition to

the Fann viscometer family. RheoVADR

®

is a direct-reading instrument for

evaluating the rheological properties of fluids, Newtonian and non-Newtonian. The
advantages of the this rheometer are its digital display, pre-programmed API tests,
data recording feature, and speed range — 12 preset and variable speeds from 0.01
rpm to 999 rpm.

This design includes a rotor, bob, torsion spring, and a stainless steel sample cup
for testing according to American Petroleum Institute Recommended Practice. This
instrument is also fitted for universal power supply.

This instruction manual supports software version 1.5.
