Designed to prepare cement slurries for testing various parameters in strict compliance with API Specification 10A/ISO 10426-1:2000
Clause 8 of API Specification 10A outlines the requirements and provides the procedure for conducting the Free-fluid Test (free water) using the Model 165AT Atmospheric Consistometer. The testing of cement slurries requires the measurement of thickening time, free water content, viscosity, rheological properties, fluid loss and various other properties.
The Model 165AT Atmospheric Consistometer provides a simple method for conditioning the cement slurries in preparation for performing these tests. This instrument is used in laboratories involved in oil well cement research programs, research and testing of cement additives, cement manufacturers quality assurance programs, and in the research for well servicing companies and their field labs.

The Model 80 Recording Atmospheric Consistometer is utilized to condition cement slurries in accordance with API Specification 10. Determination of rheological properties, examination of free water content, and evaluation of the API fluid loss test all require that the cement slurry be conditioned by an atmospheric consistometer. The OFITE Model 80 incorporates the same features as our Model 60 Atmospheric Consistometer and additionally, measures and reports temperature and consistency as a function of time via a paperless graphic recorder.
Method of Operation:A cement slurry is prepared according to the procedures outlined within API Specification 10 and then placed within the slurry containers of the Model 80 Recording Atmospheric Consistometer. The slurry is typically stirred at 150 RPM by an API-designed paddle and the temperature is increased to the desired level. The temperature is controlled by a microprocessor, which displays the process temperature via a digital indicator. Consistency, measured in Bearden Units (Bc), is determined by measuring the deflection of a calibrated spring. This deflection is created by the amount of torque that the cement slurry exerts upon the paddle and is a function of the consistency of the cement. A potentiometer mechanism generates an output voltage signal, which is directly proportional to the consistency of the cement. The graphic recorder transforms the output voltage signal into Bearden Units of consistency, which is digitally displayed and stored on disk for later analysis.

The Model 60 Atmospheric Consistometer is used for conditioning cement slurries as specified within API Specification 10. Determination of rheological properties, examination of free water content, and evaluation of the API fluid loss test all require that the cement slurry be pre-conditioned by an atmospheric consistometer. The OFITE Model 60 was specifically developed to perform these duties.
Method of Operation:A cement slurry is prepared according to the procedures as outlined within API Specification 10 and then placed within the slurry containers of the consistometer. The slurry is stirred at 150 RPM by an API-designed paddle while the temperature is increased to the desired level. The temperature is controlled by a micro-processor, which displays the process temperature via a digital indicator. Consistency, measured in Bearden Units (Bc), is determined by measuring the deflection of a calibrated spring. This deflection is created by the amount of torque the cement slurry exerts upon the paddle and is a function of the consistency of the cement. The API defines 100 Bc as 2,080 gm-cm of torque.
