The iX77™ Rheometer is a coaxial cylinder type Rheometer designed to measure fluid rheologies under high pressures and temperatures with a high degree of safety. The FANN design is based on a machine developed by the Sandia National Laboratories. It was designed with oil well and geothermal drilling fluids in mind, but has applications in many other fields. It features extensive safety interlocks through not only the internally mounted computer but also mechanical and smart electronic hardware.
Specifications of the iX77™ Rheometer allow operation to 600°F (316°C) and 30,000 psig (206,840 kPa). Optionally, a chiller may be attached and controlled by the software to allow operation below ambient temperatures.
