Rotational viscometer with direct-coupled torque transducer - no bearings
Due to the patented design, The M5600 HPHT Rheometer provides direct reading inside the pressure vessel and employs no bob shaft bearings. That means lower maintenance costs while allowing continuous testing of corrosive samples.

The only true rheology measurement under pressure
The M5600 hardware design incorporates a direct drive between the bob shaft and the torque transducer, which eliminates momentum of inertia errors associated with magnetically coupled torque transducers. This, due to the elimination of bob shaft bearings, allows the torque transducer to respond quickly and consistently to changing bob shaft torque.

Viscoelastic option available for G', G" and phase angle testing
The M5600 HPHT Rheometer does not employ magnetic coupling, instead taking direct measurements inside the pressure vessel, providing true measurement in a pressurized environment. This allows us to offer the M5600 dynamic option, which enables the user to perform true G' and G" viscoelasticity tests under pressure, without having to pre-test using fluids with known G'/G" values.

Cutting-edge database software enables customized search and data comparison
The application software, M5600 PC, includes powerful database tools for searching, categorizing, and comparing test results. The search criteria can include any test result parameter, including additives, descriptions, or other details. M5600 PC also allows you to overlap as many test charts as you like. Each test chart will display with customized graphics to differentiate it from other tests

Patented design & detailed engineering lead to highly consistent data
The unique hardware and software design of the M5600 enable it to produce test results that are extremely repeatable, because process errors and other complications are eliminated by the robust and innovative configuration of hardware and software. By removing contamination and other interference from the test environment, the M5600 test results reflect the properties of the test fluid instead of the properties of the testing hardware.

The Grace Instrument M5600 HPHT Rheometer is a true Couette, coaxial cylinder, rotational, high pressure and temperature rheometer (up to 2,000 psi and 500°F).

The M5600 HPHT Rheometer is also available with an optional viscoelastic module for performing viscoelasticity tests to derive G', G”, G* and phase angle. This vastly increases the researcher's ability to predict the behavior of fluids, such as their capacity for suspending and carrying solids (weight material sag, drill cuttings transport, proppant transfer, etc.)

In the field of rheology-measuring equipment, only the Grace Instrument M5600 HPHT Rheometer offers true visco-elasticity measurement under pressure. Due to the patented design, The M5600 HPHT Rheometer provides direct reading inside the pressure vessel and employs no bob shaft bearings. That means lower maintenance costs while allowing continuous testing of corrosive samples.

Other rheometers often utilize a magnetic coupling across a pressure vessel to rotate a magnet on a bob shaft, using metal or air bearings, in order to measure viscoelasticity. A calibration fluid with known G'/G" values must be tested to provide a baseline for viscoelastic measurement. However, when the tested fluid possesses different G'/G" values compared to the calibration fluid, G'/G" measurement will be invalid.

The M5600 HPHT Rheometer does not employ magnetic coupling, instead taking direct measurements inside the pressure vessel, providing true measurement in a pressurized environment. This allows the user to perform true G' and G" viscoelasticity tests under pressure, without having to pre-test using fluids with known G'/G" values.

The M5600 HPHT Rheometer incorporates a direct drive between the bob shaft and the torque transducer, which eliminates momentum of inertia errors associated with magnetically coupled torque transducers. This, due to the elimination of bob shaft bearings, allows the torque transducer to respond quickly and consistently to changing bob shaft torque.
