Germann Instruments has unveiled ICAR Plus Rheometer, citing a
strong motor, personalized electronics and more comprehensive soft-
ware than the predecessor model. ICAR Plus' principal advantage is a
digital calibration process affording operators a ready to use system
under any environment and working condition. Calibrated on-site,
it can be verified in the laboratory with the same silicone as the
ICAR Rheometer.
After every digital calibration, ICAR Plus software displays the
uncertainty torque measurement value, typically less than 0.5 per-
cent, along with Torque vs. Time function during the stress growth
or flow curve test. The software controls the one-minute tests and
computes static and dynamic yield stresses, plus plastic viscosity in
fundamental units. If the raw data of every test is saved, stress growth
and dynamic flow curve plots can always be displayed.
ICAR Plus suits concrete of 3-in. or greater slump and bearing
maximium 1.25-in. aggregate. It is equipped with an integrated servo
motor and has a vane rotation speed of 0.001 to 0.667 revolutions/
second. The new rheometer includes motor drive, base frame, vane,
power supply and cables. Along with carrying case, it weighs about
45 lbs. — Germann Instruments, Evanston, Ill., www.germann.org
