INTRODUCTION
Overview
The CANNON®High-Temperature High-Shear (HTHS) Series II Vis-
cometer is designed to determine the viscosity of engine oils and other
oils under conditions of high shear at high temperatures.
The HTHS Series II is capable of testing at a temperature of 150°C as
specified in ASTM D 5481. For other applications, temperature may be
set as low as 25°C above ambient.
Oil samples are introduced into the viscometric cells and then propelled
through the glass capillary tubes at the test temperature to obtain various
shear rates. The HTHS Series II monitors the test and records the results.
Data can then be analyzed via the computer software and test results can
be displayed and printed.

NOTE The CANNON®High Temperature High Shear Series II Viscometer
meets the high shear testing requirements of ASTM D 5481. SAE J300
(DEC99) requires HTHS viscosities from 2.6 to 3.7 mPa•s. Because the
HT75 standard has a nominal viscosity of 2.7 mPa•s and the HT150
standard has a nominal viscosity of of 3.7 mPa•s, CANNON®recom-
mends that the users calculate cell volumes using either of these stan-
dards.

Apparatus description
WARNING! The HTHS has been designed for testing of hot oil samples under high
pressure. Care should be taken to perform sample tests per the proce-
dures described in this manual.
The High-Temperature High-Shear Series II Viscometer consists of a
heating device (an aluminum thermostatic block) with cavities housing
five viscometric cells. The block permits temperature regulation of the
test sample from 30°C to
150°C, ± 0.1°C. Compo-
nents and accessories
include the waste-oil
receiver, Vacuum Pressure
Unit (built-in), digital timer
mechanism, soak cycle
timing watch, thermal
sensors and safety devices.
Waste-oil receiver
The waste-oil receiver (see
photo) consists of a recess
underneath the block with
apertures for the exit tubes
from the five test cells. Aplastic container is placed under the tubes to
catch the oil sample as it is expelled from the viscometer cells. The
container slides into place at the left front of the HTHS Series II. A
hinged door provides protection from hot oil. At the rear, an internal fan
draws vapors into the exhaust manifold.
Cell capillaries
Each viscometric cell contains a borosilicate-glass capillary sealed with
Viton®gaskets at each end. A capillary support seats the capillary tube in
the cell.
NOTE Matching of capillary
lengths from one test
cell to the next within
1 mm will allow the
individual cell
calibrations to be
more closely
matched, making
subsequent runs of identical sample in different cells more repeatable.
Matched capillary sets supplied with the instrument at initial purchase
and are also available for purchase from CANNON®.
Nitrogen supply
The user-supplied nitrogen gas cylinders should be fitted with a pressure
regulator to reduce the pressure supplied to the HTHS Series II to no
more than 500 psi. Testing pressures will range from 100 to 500 psi.
CAUTION Nitrogen is the only gas recommended as a source of pressure for the
HTHS Series II viscometer.

Operation
Oil is introduced into the cells via the syringe-like
charge cylinder(s) (see photo). The oil sample is
filtered through a screen, then warmed to test
temperature in the viscometric cell and finally
propelled under high pressure from the cell through
a narrow exit tube. The oil sample is expelled into
a plastic container in the waste-oil receiver. A
digital timer tracks the duration of the test run.
Safety features:
Protective housing The HTHS components are protected from damage
by a sturdy metal housing. The housing also
prevents direct operator contact with the heater
block assembly.
Pressure relief The HTHS ballast tank stores pressurized gas from
the user nitrogen supply for the HTHS. If pressure
in the tank exceeds 700 psi, the internal HTHS
pressure relief rupture disc will vent gas to atmo-
sphere until the gas source is turned off or depleted.Afailed rupture disc
must be replaced prior to resuming HTHS operations. See APPENDIX B
for additional information on rupture disc replacement.

assembly
Thermostat The HTHS Series II is equipped with a thermostat that prevents the
instrument from overheating. If temperature rises to an unacceptable
level (160°C ± 5°C), power will be removed from the HTHS and will not
be restored until the instrument has cooled to a safe state.
