 M 7500 Ultra HPHT Dynamic Rheometer 
 The Grace Instrument M 7500 Ultra HPHT Dynamic 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 M 7500 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 M 7500 ’ s 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 . 
 The M 7500 is engineered for safe testing with extreme pressure and temperature settings :

 More M 7500 add - on modules : 
 M 7500 add - on modules provide powerful new functionality at a lower cost than competing , stand - alone instruments , while maintaining a single instrument footprint and merging seamlessly with your existing software training . Click the tabs below to explore the various additional options available . 
 M 7500 PVT Ultra HPHT Pycnometer : 
 The M 7500 PVT Ultra HPHT Pycnometer module measures dilametric changes inthe density of a solid or fluid sample under conditions of temperature and pressure overa period of time . The patented M 7500 PVT Ultra HPHT Pycnometer replaces components of the M 7500 Rotor / Bob assembly . 
 More specifications and other information can be found on our M 7500 Ultra HPHT Pycnometer page . 
 M 7500 LSM Linear Swell Meter : 
 The Grace Instrument M 7500 LSM Ultra HPHT Linear Swell Meter is an add - on module for the M 7500 Ultra HPHT Rheometer and provides an automated , ultra - high pressure and high temperature linear swell meter ( up to 30 , 000 psi and 600 ° F ) . Like the dedicated Grace Instrument M 4600 HPHT Linear Swell Meter , it is engineered to measure the volumetric expansion ( or contraction ) of a solid sample under simulated downhole conditions while saturating it with a fluid sample . 
 More specifications and other information can be found on our M 7500 LSM Linear Swell Meter page . 
 M 7500 HPHT Cement Rheometer : 
 The HPHT Cement Rheometer is an engineered insert for the M 7500 Ultra HPHT Rheometer that is designed for testing cement samples . 
 The cement sample is contained entirely within the rotor assembly , reducing contamination with pressurization fluid to a bare minimum . Once testing is finished , the rotor can be quickly disassembled for easy cleanup . 
 The patented design of the cement cell module eliminates jewel bearings , thus preventing measurement errors which can occur when bearings become contaminated with sample fluids . 
 M 8500 HPHT Sag Tester : 
 The M 8500 High Pressure , High Temperature Dynamic Sagging Tester is designed for evaluating barite and other weight material sag under simulated drilling conditions . ( The M 8500 option must be specified at time of purchase . ) 
 More specifications and other information can be found on our M 8500 HPHT Sagging Tester page . 
 M 7500 Ultra HPHT Dynamic Rheometer Carrying Case 
 The M 7500 Ultra HPHT Dynamic Rheometer Carrying Case comes in two pieces : one unit contains the cell tower and magnets , the other unit contains the control cabinet and all connecting hardware .
