Bath Construction and Safety Features - Bath chamber is a clear Pyrex®
vessel enclosed in a polyester-epoxy finished steel housing. Top working
surface has seven 2" (51mm) viscometer ports. Front viewing window assures
safe, distortion-free viewing. Microprocessor temperature controller
incorporates safety circuitry that interrupts power to the heaters in the event
of an overtemperature condition or disconnection of the primary probe. For
added safety, an adjustable redundant controller with separate sensor probe
interrupts power if an overtemperature situation occurs. An integrated lowliquid sensor prevents operation of the bath if the bath liquid is not filled to the
proper level, and cuts off power should it fall below during operation. Both
overtemperature and low liquid level circuits will latch and prevent further
operation of the bath until the fault is removed.

Calibrated Glass Capillary Kinematic Viscometers
Koehler offers a full selection of glass capillary viscometers for measuring
kinematic viscosity of liquid petroleum products in accordance with ASTM
D445 and related standard test methods. All types of viscometers conform to
ASTM D446 and related standard specifications for glass capillary kinematic
viscometers. Each viscometer is supplied with a calibration certificate, and
holders should be ordered separately. Please refer to the following brief
descriptions for determining which viscometer is best suited for your
particular application.
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. Other
viscometers for transparent samples in this catalog include the Cross Arm and
BS/U-Tube viscometers.
Ubbelohde Viscometers
The Ubbelohde viscometer and other suspended level viscometers are used to
measure transparent liquids. Unlike the Cannon®-Fenske Routine viscometer,
suspended level viscometers maintain the same viscometer constant at all
temperatures, advantageous when samples are to be measured at different
temperatures. Other suspended level viscometers in this catalog include the
BS/IP/SL, BP/IP/SL(S), and BP/IP/MSL viscometers.
Reverse Flow Viscometers
The Cannon®-Fenske Opaque, Cross Arm, and BS/IP/RF U-Tube viscometers
have been 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.

Several semi-micro viscometers have been designed which require one
milliliter or less of liquid, which include the Cannon®-Manning Semi-Micro,
Cannon®-Manning Semi-Micro Extra Low Charge, and Cannon®-Ubbelohde
Semi-Micro viscometers.
For kinematic viscosity of transparent liquids up to 20,000cSt. Requires a
sample of approximately 7mL. Use with K23310 and K23350 rectangular
metal holders or K23381 and K23351 round plastic holders.

Estimates of the molecular size and shape of large polymers molecules can be
obtained from kinematic viscosity measurements of dilute solutions. The
Cannon®-Ubbelohde Dilution viscometer has an extra large reservoir which
allows polymer solutions to be diluted several times and measures viscosities
at four different shear rates. Dilute polymer solutions frequently appear to
exhibit changes in kinematic viscosity when the shear rate is changed.
Vacuum Viscometers
In most glass capillary viscometers, the samples flow under gravity. When
liquids are too viscous to flow readily under gravity, vacuum viscometers may
be used to measure viscosity. A vacuum is applied to one end of the
viscometer to pull the liquid through the capillary into the timing bulb. Koehler
offers the Cannon®-Manning Vacuum, the Asphalt Institute Vacuum, and the
Modified Koppers Vacuum reverse flow viscometer tubes. These vacuum
viscometers require an accurately controlled vacuum regulator for proper
measurement. Please refer to page 13 for information about the Koehler
Vacuum Regulator.

Constant temperature liquid bath permits testing of samples without the risk
of sample temperature rise. After cooling in the air bath, the sample must be
transferred to the balsa cell carrier for testing with the Brookfield viscometer.
If the sample is not tested quickly, there is the risk of sample temperature rise.
The Brookfield Viscosity Liquid Bath eliminates this risk by permitting the
sample to be tested in a constant temperature environment. The Brookfield
viscometer mounts directly on the bath and the samples are rotated into
position under the spindle by means of a built-in turntable. Cooling system
maintains temperature with ±0.05°C stability in the range of +10°C to –55°C.
Bath temperature is displayed in digital format.

Liquid Bath
• Sample soaking and testing in a single bath, eliminating the need for an
air bath and the risk of sample temperature rise during transfer
• Redesigned for improved control of sample movement and handling
during testing
• Microprocessor PID temperature control duplicates the sample cooling
rates in ASTM D2983
• Up to 40 cooling/testing temperature profiles can be stored in memory
Redesigned programmable baths with improved features for sample handling
and testing. Bath accommodates 10 samples for Brookfield Viscosity testing.
Sample cells are immersed in a liquid bath for the entire soaking and testing
period, eliminating the need to transfer cells from an air bath to a liquid bath
with insulated balsa wood carriers. Also eliminated is the inherent risk of
sample temperature rise during transfer. The programmable microprocessor
PID controller stores up to 40 temperature profiles that duplicate the sample
cooling rates found in ASTM D2983. Steady state temperature accuracy and
uniformity exceed ASTM requirements throughout the operating range from
ambient to -55°C. Air-cooled hermetic compressors provide efficient operation
with the use of CFC-free refrigerants.
The mounting position for the Brookfield Viscometer has been changed to
permit easier access to the samples and viscometer controls. Cabinet has a
front window and glare-free fluorescent lighting for distortion free viewing of
the sample cells. Cabinet construction is polyester-epoxy finished steel with a
chemical-resistant composite top surface. A removable insulated cover with
handle is included. Bath rests on adjustable leveling feet. Safety features
include a probe fault detection circuit in the primary temperature controller and
a redundant latching controller and probe for temperature fault protection.

Viscosity Standards
Viscosity Reference Standards
• Manufactured and certified according to ASTM D2162, the primary
method for viscosity reference standards
• Supplied with an ISO/IEC 17025 Certification Report
• Fully compliant to ASTM and related test procedures
• Custom standards available
Koehler viscosity reference standards are used for calibration and verification
of kinematic and dynamic viscosity test equipment, both manual and
automatic. All viscosity standards are based upon the National Institute of
Standards and Technology (NIST) value of 1.0034 cSt (Centistokes) for water
at 20°C (68°F). All standards are traceable to National Standards and are
manufactured and certified according to ASTM D2162, the internationally
recognized primary method for viscosity reference standards, under
ISO/IEC 17025 guidelines. Standards are calibrated to a precision of ±0.2% for
the viscosity and kinematic viscosity. Nominal or approximate values are listed
in the following tables. With each standard, actual certified values for kinematic
viscosity (cSt), dynamic viscosity (cP), and density (g/mL) according to ASTM
D1480 are provided at each temperature point of calibration along with
uncertainty measurements. Each standard is calibrated at a minimum of five
temperatures and supplied in a 500mL quantity in an amber-colored bottle
complete with full certification and a Material Data Safety Sheet (MSDS).
In addition to the many viscosity standards described in this catalog, we can
supply custom viscosity standards made specifically to meet your individual
needs including high volume supply used for Statistical Quality Check and
Statistical Process Control (SQC/SPC) applications.

Viscosity Standards
Important Information About Viscosity Standards x
All Koehler certified viscosity standards are Newtonian fluids manufactured
from high stability base oils and polybutenes. The standards have an
expiration date on the label at least twelve months or longer from the date of
purchase. With time, changes resulting from slow oxidation or loss of volatiles
may occur. These changes can be minimized by storing the standard in the
closed bottle at ambient laboratory temperatures and out of sunlight. The
expiration date on the label is part of Koehler’s program of total quality control
and is intended to ensure that the standard will be utilized while the certified
viscosity data remains valid.

Viscosity
Test Method
This viscosity technology is based on a simple and reliable electromagnetic
concept. Two coils move the piston back and forth magnetically at a constant
force. Proprietary circuitry analyzes the piston’s two-way travel time to
measure absolute viscosity. Built-in temperature detector (RTD) senses the
actual temperature in the sampling chamber. Constant in and out motion
keeps samples fresh and mechanically scrubs the sampling area.
