Revolutionizes Consistency and SGS Measurement Tests
The patented Grace Instrument M7540 HPHT Consistometer/SGS Tester measures slurry consistency, thickening time, and static gel strength all in one test while the slurry is subjected to simulated downhole conditions. This unit’s innovative hardware design prevents hydraulic fluid from mixing with the test sample and includes roller bearings on the paddle shaft that minimizes friction measurement errors.

Choose from two different testing paddles, a standard API paddle for consistometer testing or a MACS II®-Style SGS paddle for static gel strength testing. FREE advanced software included with each unit allows the user to construct test sequences, run tests, and interpret test results quickly and efficiently.

Robust Components Provide Exact Measurements
This unit features a rotating paddle that turns at speeds up to 250 rpm. Cement slurry is placed in a temperature-controlled, pressure-controlled cell tested under user-specified conditions via the accompanying software. The paddle is driven by a servo through a magnet coupling. The servo reads the torque to determine the slurry consistency or static gel strength. The max rated torque for the M7540’s motor is 0.637 N·m, and the torque resolution is 9.72e-6 N·m. All hardware components are created in accordance with industry-standard API specifications.

Simple Setup, Easy Operation, and Reliable, Repeatable Testing
The M7540 enables the operator to perform accurate, dependable test operations with minimal preparation time. Its unique design prevents the mixing of pressurization fluid with cement due to stirring. The M7540 is also easy to set up, use, and clean.

To ensure operator safety, the software includes several innovative safety features. The software will shut down tests with a reaction torque measurement above 1800 lb/100 ft2. It can also be set to automatically stop the motor at the end of or during tests, end tests, program the heating speed to increase/decrease temperature step-by-step, enable an alarm that activates when set values of temperature and consistency are exceeded, and more.
