controller calibration. If the controller
needs to be calibrated, then please
contact the Koehler technical service
department.
6. Viscometer Ports: The viscometer,
once engaged into the assembly, is
placed into the bath through the
viscometer ports on top of the
instrument.
7. Bath/ Bath Stirrer: The stirrer
constantly circulates bath medium to
prevent temperature gradients and
ensures temperature stability. When
cleaning and/or servicing, please be
sure to disconnect unit power to avoid
possible injury.
8. LCD Timer Display: Displays time of
fluid flow through viscometers and is
manually controlled by the operator.
Time is recorded in seconds to one
decimal place.
9. Timer Start/Stop: Depressing this
button starts or stops the manual timer
operation.
10. Timer Reset: Depressing this button
resets timer to zero (0.0) whether the
timer is in operation or stopped.
4.2 Accessories for Running Tests
Glass Capillary Viscometer Tubes for
KV3000
Koehler offers a full selection of glass capillary
kinematic viscometers, which are ordered
separately from the KV3000 instrument, for
measuring kinematic viscosity of liquid products
as per ASTM D445 and related standard test
methods. All types of viscometers conform to
ASTM D445 and related methods for glass
capillary kinematic viscometers. All viscometers
with part numbers for the automatic test are
listed below. The constant for each individual
viscometer is written on the Certificate of
Calibration, included in the packaging.
IMPORTANT: It is recommended when using a
new viscometer for the first time to run a test
with suitable standard. Different locations may
result in a slightly different constant.
Cannon®-Fenske Routine Viscometers
The Cannon
®
-Fenske Routine viscometer is a
rugged and inexpensive viscometer that works
well if the sample is transparent or translucent.
For kinematic viscosity of transparent liquids
up to 20,000cSt.
Requires a sample of approximately 7mL.
Cannon®-Fenske Opaque Reverse Flow
Viscometers
The reverse flow viscometers are designed for
testing opaque liquids. These viscometers wet
the timing section of the viscometer capillary
only during the actual measurement and must
be cleaned, dried and refilled before a repeat
measurement can be made. By contrast, other
viscometer types commonly used to measure
transparent liquids allow the sample to be
repeatedly drawn up into the capillary, permitting
duplicate measurements.
For measurement of transparent and dark
liquids having kinematic viscosities of up to
20,000cSt
Requires a sample of approx 12mL.
Can be used for viscosities of asphalts by
ASTM D2170 method.
