The Model 800 8-Speed Electronic Viscometer is designed and exclusively
manufactured by OFI Testing Equipment, Inc. It is extensively used worldwide
in both the eld and laboratory for the precise measurement of rheological
properties of uids.
The OFITE Model 800 Viscometer determines the ow characteristics of oils
and drilling uids in terms of shear rate and shear stress over various time
and temperature ranges at atmospheric pressure. Speeds are easily changed
with a control knob, and shear stress values are displayed on a lighted
magnied dial for ease of reading.
The viscometer’s motor RPM is continuously monitored and automatically
adjusted by the OFITE Pulse-Power electronic speed regulator to maintain
a constant shear rate under varying input power and drilling uid shear
conditions. The eight precisely regulated test speeds (shear rates in RPM)
are as follows: 3 (Gel), 6, 30, 60, 100, 200, 300, and 600. A higher stirring
speed is also provided. Speeds may be changed with a control knob
selection, without stopping the motor.
The Model 800 is suitable for both eld and laboratory use and uses a
motor-driven electronic package to provide drilling uid engineers with
an extremely accurate and versatile tool. The Model 800 operates from a
13–16 VDC power source. The electronic regulator continuously monitors
and automatically adjusts the rotational speed to maintain a constant shear
rate under varying uid shear conditions and input power variations that are
commonly found on-site.
