General Information
Introduction
This manual contains installation, operation, and maintenance instructions for the Chandler
Engineering Model 1200 Atmospheric Consistometer.
Purpose and Use
The Chandler Engineering Model 1200 Atmospheric Consistometer is used for various tests
of oil well cements as detailed in the American Petroleum Institute Specification for
Materials and Testing for Well Cements - Specification 10A (API Spec 10A). The apparatus
is used in conjunction with tests for:
•Determination of Water Content of Slurry
•Determination of Fluid Loss
•Determination of Rheological Properties of Cement Slurries
Description
The Chandler Engineering Model 1200 Atmospheric Consistometer consists of a stainless-
steel water bath that houses two slurry containers. The instrument front panel contains a
microprocessor-based temperature controller that also serves as a digital temperature
indicator. The temperature controller operates a relay that controls a 1500-watt heater. The
Model 1200 includes cooling coils as a standard feature.
Lighted switches that also serve as circuit breakers are installed in the front panel. The
circuit breaker function of these switches eliminates the necessity for in-line fuses.
Units of consistency for the cement slurry are directly indicated on the top dials of the slurry
containers. Slurry consistency is expressed in Bearden units of consistency, Bc, where 100
Bc is equivalent to the spring deflection observed with 2,080 grams-centimeter of torque
(400 grams weight) using the weight-loaded calibrating device. For further details, refer to
API Spec 10A.
The slurry containers are rotated by engaging the pins of the lid with the slots on the rotator.
The rotators are fitted with timing sprockets driven by the motor, which is factory set at 150
rpm. The belt also drives an impeller that agitates the water bath. The motor should be
turned off before engaging or disengaging the slurry container.

Calibration Procedure
Before calibration and operation of the instrument, the paddle should be tested for excessive
friction by running the slurry container without cement inside. If the paddle is bent so that it
rubs on the side, appreciable movement will be shown on the indicator. The bearings in the
slurry-indicating lid should be checked for excessive friction. Any abnormality should be
corrected before proceeding with the instrument calibration.
Calibration and operation of the instrument is described in API Spec 10A. This instrument is
equipped with a calibrating spring and can be calibrated using the calibration device and
adapter. The adapter is placed with screws on the right-rear side of the calibration device,
and the ring rests on top of the lid. The roller located on the right-front side of the calibration
device is raised to a position so that the cord is level with the lid.
Refer to Figure 5 for the following:
1. Place the container lid on the calibration assembly.
2. Place the adapter ring on the container lid assembly.
3. Place the cord counterclockwise around the lid and attach 300 grams of weight.
4. Pull the weight down slightly and release a few times to obtain an average reading.
The indicator should read “7.5” (75 Bc 5 Bc).
5. Corrections can be made by turning the small set screw to loosen the spring clamp
inside the lid.
6. Slide the spring to the right when the indicator reads below “75” Bc.
7. Slide the spring to the left when the indicator reads above “75” Bc.
8. After the spring is adjusted, loosen the top nut and set the indicator hand to “0”Bc.
9. The “75” Bc must be re-checked.
10. Repeat steps 1 through 9 until “0” and “75” Bc are correctly indicated within 5 Bc.
11. When the spring has been adjusted to read 75 Bc with 300 grams, several points
should be checked, such as 25 Bc –100 grams, 50 Bc –200 grams, and 100 Bc –400
grams.
