The Fann Model 50SL High-Temperature Rheometer is a rotational viscometer designed for testing drilling fluids and fracturing fluids at temperatures up to 500°F (260°C) and pressures up to 1,000 PSIG (7,000kPa) in a coaxial cylinder chamber. Heating, pressurization and rotor speed are controlled by input from specialized software.

The  xpRt50™ software is optimized for use with drilling fluids and fracturing fluids, and is designed to allow a single computer to control two Model 50 Viscometers using RS-485 serial communications. Once the sample has been loaded and the heater bath raised for testing, all control of the viscometer is accomplished via the computer and the specialized software.

The torsion springs are designed for ease of interchangeability, which permits the shear stress range of the instrument and, hence, the viscosity measuring range to be optimized for a given testing problem.
