M250

Atmospheric Consistometer

Model #: M250

Description

CTE Model 250 Atmospheric Consistometer is specifically designed to prepare cement slurries for the testing of various parameters in strict compliance with API Spec 10 and ISO 10426. The testing of cement slurries requires the measurement of thickening time, free water content, viscosity, rheological properties, fluid loss and various other properties. Maximum operating temperature of 250F (121C). The Model 250 provides a simple method for conditioning the cement slurries in preparation for performing these tests. API Spec 10 outlines the requirements and provides the basis for the design and operation of Atmospheric Consistometers. Cement slurries are initially mixed with a CTE Model 7000 Constant Speed Mixer in compliance with Section 5 of API spec 10.

M250 Operation Manual

The slurry is then placed into the Model 250 for any or all of the following tests as per API and ISO requirements:

✔ THICKENING TIME
✔ WATER CONTENT OF SLURRY
✔ DETERMINATION OF RHEOLOGICAL PROPERTIES
✔ FLUID LOSS TEST

The Model 250 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.

OPERATION

The cement slurry is prepared in accordance with Section 5 of API Spec 10, and then quickly poured into either of two available slurry containers in the unit. The stirring paddle is inserted and the lid placed on the container. The container is then placed into the temperature-controlled water bath and stirring is started. The unit is designed so the stirring operation can begin within one minute or less, in compliance with API Spec 10. The integrated Eurotherm nanodac allows simple operation and calibration. Consistency and temperature are displayed and automatically recorded via USB or ethernet connection. Data is then transferred to PC and plotted via viewing software or can be imported to spreadsheet software. No more expensive paper strip charts and ink pens to replace.

FEATURES

✔ Analog to digital potentiometer mechanism.
✔ Color digital recorder for both temperature and consistency displays in real time.
✔ Beautifully combined Eurotherm nanodac digital recorder and temperature controller.
✔ Simple data transfer to spreadsheet via .csv file format or Eurotherm View Software.
✔ Leading industry design incorporating stainless steel paddle casting and replaceable shaft.
✔ Adjustable rpm.
✔ Heavy duty motor gives years of trouble free operation.
✔ Copper cooling coil integrated into stainless steel tank for fast cooling.
✔ Heavy duty, long lasting, stainless steel ball bearings.
