Description:


Patented design prevents sample contamination
The Grace Instrument M7500 Ultra HPHT Rheometer is a coaxial cylinder, rotational, high pressure, and high temperature rheometer. It is engineered to measure various rheological properties of fluids (including API HPHT tests) under a range of pressures and temperatures, up to 30,000 psi and 600°F. An optional cement module is also available for testing the rheology of cements (see tab "Cement Rheometer", below.)

The Grace Instrument M7500 Ultra HPHT Rheometer employs a unique, patented design which entirely prevents contact between sample fluid within the main test chamber and pressurization fluid, which is injected into interlocking isolated chambers above the test chamber. No other rheometer on the market today can make this claim.

Optional components add multiple test functions while saving time, money, and laboratory space
Hardware modules are available which add specific functionality to the M7500, including cement testing, pressure/volume testing, linear swell testing, and more. These modules take the place of stand-alone equipment and can be integrated into the standard M7500 training program, saving training time and consolidating test times. This feature alone enables the M7500 Ultra HPHT Rheometer to provide an excellent ROI.

 

Features:

  • The M7500 is built with a thick-walled steel pressure cell, which is surrounded by a fail-safe steel containment vessel to ensure operator safety.
  • It is designed for easy test set up, sample loading and post-test cleaning.
  • Cool-down after tests can be accomplished more quickly by connecting a tap water supply or a chiller into the M7500 cooling fluid loop.
  • Innovative patented design ensures against contamination of test sample with pressurization fluid.
  • Recently patented design eliminates the need for fragile and expensive "V" jewel bearings.
  • A computer-controlled, magnetically-coupled stirrer agitates the sample during testing
  • Provides users with sturdy unit, safe operation, and low maintenance
  • Engineered for safe testing with extreme pressure and temperature settings
  • Offers repeatable results and test flexibility
  • Unit includes an LCD screen and PC interface
  • Instrument does not compromise sample integrity
  • Fully digital and automatic
Comparison between Grace M7500 and Leading Competitor
  Grace M7500 Competitor
Bearings Patented and patent pending design eliminates jewel bearings. Use ball bearings. Easy to replace.
Very economic.
V Shape jewel bearings. Fragile, easy to break, difficult to install, very expensive.
Mixing with Pressurization Fluid Patented and patent pending design prevents tested sample to mix with pressurization fluid as long as tested sample is compressed less than 23% of volume. Tested sample will mix with pressurization fluid when tested sample is compressed more than 2.5% of sample volume.
Speed Range Standard range 0.01 to 600 RPM. 3 to 600 Rpm continuously.
Electronics Almost all electronic components are from third party reputable companies with excellent quality tracking records. Easy to replace in the future. Majority of the electronics are special designed PCB by fann Instrument. Easy to break down. Very difficult to replace and re-calibrate. Very expensive to maintain.
Operation Patented and patent pending design very easy to operate. Test turn around time is about one quarter of fann 75. No need for re-calibration before every test. Need special training to perform testing. Very difficult to operate due to extremely complex mechanical designs. Need calibration before every single test. Very difficult to calibrate too.
Software State of the art PC software with Database engine, real-time charting, various 2D & 3D charts, and unlimited chart overlapping. Database management of test results, searchable by test name, additives, etc. Limited functions designed almost 10 years ago.
Calibration Automatic shear stress calibration. Requires user to go through some complicated steps and mechanical adjustment before able to start calibration.
Weight & Dimensions Separate cell tower and control cabinet. Smaller foot print, height and weight. Movable by two personnel One integrated unit. Can only be moved by 4 people. Dangerous to move around due to its whole weight.
