5.1 Bath
Fill the bath with the appropriate heat transfer
fluid based upon the testing temperature. Fill the
bath with the medium from the top through one
of the seven port openings using a wide neck
funnel with a 500mL griffin beaker adding about
½ L at a time to 2" (5 cm) from the top of the
bath to allow room for fluid expansion. This will
provide the proper depth for immersing the
viscometers and allow for thermal expansion.
NOTE: Do not attempt moving the bath
when filled with fluid medium. Drain all fluid
using the drain valve at the back of the
instrument before moving or relocating. Sudden
starting and stopping could result in hot bath
fluid being forcefully ejected from the bath. It
could also result in overbalancing and tipping
over the instrument.
NOTE: Do not drain the bath until the fluid
is at ambient temperature.

50 - 95°C Koehler supplies highly
refined white technical oil
(part # 355-001-001) that
contains an oxidation inhibitor
to limit clouding at higher
temperatures.
CAS# 8042-47-5
Minimum Flash Point: 120°C
(248°F)
Fire Point: 202°C (395°F)
NOTE: Do not use bath fluids that will
decompose or volatilize producing flammable
vapors below the maximum instrument operating
tempe25°C.
NOTE: Coloration of the Mineral Oil is an
indication that the Medium must be changed.
See Draining instructions in section 7.3 of this
document. When a decision is made to discard
this material, dispose of this material and its
container to a hazardous of special waste
collection point. Country, State, or local laws
may impose additional regulatory requirements
regarding disposal. Dispose in accordance to all
applicable regulations.
WARNING: Bath oils contaminated with
light ends can pose a flammability hazard.
5.2 Power
Turn on the main power switch to the unit.
WARNING: Do NOT turn the power on
unless the bath is filled with the proper medium;
otherwise, damage may occur to the unit and
the warranty would be void.
5.3 Starting a Test
Before running a test, make sure the unit is
level. Otherwise, the results will be affected.
1. Install an appropriate ASTM thermometer or
PT100 Temperature in the cover plate of the
bath using the holder provided.
2. Verify Temperature controller calibration in
accordance to an external temperature
reader and set the desired operation
temperature using the temperature controller
(See Section 4.3 for full operational details).
3. Prepare and place up to seven samples into
the sample holders on the top front of the
unit and lower until bottom of cylinder is in
complete contact with the metal base.
WARNING: Do not test or run materials
that boil or exhibit high vapor pressure at the
bath test temperature.
IMPORTANT: Allow the bath AND the sample
enough time to reach the temperature before
starting measurements. Allow 10-15 minutes
for the bath to equilibrate. Do not add medium
to the bath while a test is being performed.
Additional medium will disrupt the temperature
