M7800 Ultra HP/HT Hematite Rheometer
- Height: 22 in.
- Width: 12 in.
- Depth: 24 in.
- Weight: 280 lbs.
- Max Pressure: 40,000 psi | Max Temp: 600°F
- U.S. Patent: 8,813,542
Designed to completely isolate magnet from testing sample
The U.S. patented design allows separation of magnet from testing samples, and is especially suitable for hematite types of mud and liquid samples reactive to magnets.
Engineered to provide ultra-high pressure testing & easy operation
The M7800 HPHT Hematite Rheometer can apply pressure to the pressure chamber as high as 40,000 psi, giving the researcher a pressure environment range greater than any competing instrument, while providing easy operation and simple maintenance.
Unlike the standard operation of a rheometer which operates via magnetic coupling, the Grace Instrument M7800 Ultra HPHT Hematite Rheometer is configured to keep the magnets completely separated from the tested fluid. This helps ensure that test results are free of magnetically-induced errors.
Simple Setup, Easy Operation, Reliable & Repeatable Testing
The patented M7800 design modifies the M7500 cell tower hardware to enable test pressures of up to 40,000 psi. Like the M7500, The M7800 is built with a thick-walled steel pressure cell, which is surrounded by a fail-safe steel containment vessel to ensure operator safety.
