Temperature selection
This manual is intended to provide information on the installation, characteristics and operation of the CANNON
T emperature Baths. CT-500 references in the manual will apply to all
models unless otherwise indicated.
The CANNON® CT-500 series II Constant Temperature Baths are
designed to be used for precise viscosity measurements. Because of its
temperature stability and ease of use, the baths are also suitable for many
other applications where temperatures must be maintained within
± 0.01 °C.
The CANNON® CT-500 will maintain temperatures of 20°C to 100°C
± 0.01°C. The CT-500 includes a built-in cooling coil which, when
connected to tap water or a cooling system, permits operation below or
slightly above ambient temperature. The cooling coil should be used
when controlling temperature within 10°C of ambient.
The precision of kinematic viscosity measurements possible with the CT500 system meets the sensitivity requirements of ASTM D 445.
Ten of the most
commonly-used
temperatures for
kinematic viscosity
measurement can
be set using the
left-hand dial on
the bath front
panel. The bath
will equilibrate
within a fraction of
one degree of the
desired temperature. A fine-tuning
control permits
further temperature adjustments.
By switching to
the variable setting
on the front panel,
the operator can set any temperature within the operating range of the
instrument.

The bath chamber is a cylindrical clear Pyrex® vessel 300 mm (12
inches) in diameter and 300 mm (12 inches) high. A stainless steel baffle
coated with white PTFE is located in the center of the bath and provides
a convenient backdrop for viewing viscometers placed in the bath. The
top cover contains seven round holes 51 mm (two inches) in diameter for
insertion of viscometer holders. An additional 10 mm (3/8 inch) hole is
provided for a thermometer.
A solid-state control circuit provides proportional control of the temperature. The sensing element for the control circuit is a stainless steelencased thermistor. The entire electrical control system is located in a
drawer beneath the bath.

Safety features
The CT-500 comes equipped with a number of safety features:
Temperature fault sensor
Thermistor cutoff detection
Bath fluid level cutoff
NOTE
Operator safety
A second thermistor in the temperature bath senses any over-temperature
fault condition. If such a condition occurs, all power is removed from the
bath until an operator corrects the problem and resets the over-temperature limit circuit.
If the control thermistor is disconnected, all power to the bath heaters is
cut off.
The CT-500 will not operate if the liquid level in the bath is too low. If
such a condition occurs, all power is removed from the bath until the
liquid level in the bath is restored to the minimum safe level.
Safety devices may be impaired if equipment is not operated per manual
instructions.
All technicians who use the CT-500 should follow these basic safety
procedures:
• The CT-500 power cord should only be connected to a suitable AC
mains power source (with protective earth ground) matching the
specifications of the S/N label on the CT-500 rear panel.
• The CT-500 should be placed on a stable laboratory table or bench.
• If any liquids are spilled in or around any electronic components of
the CT-500, remove power and contact CANNON
®
Instrument
Company before introducing power to the system again.
• Position power cords so that they are not likely to be walked on or
pinched by items placed on or against them. Keep all connections as
neat as possible.
• To disconnect the power cord, pull it out by the plug. Never pull the
cord itself.
• Do not attempt to service the CT-500 system by removing panels and
trying to effect repairs. Contact CANNON
®
Instrument Company for
all service and repair needs.
• Monitor bath fluid level carefully and use caution when operating at
temperature set points above ambient temperature. Liquid may
expand and overflow the jar.
• Observe appropriate safety precautions when handling bath fluid
(refer to the Material Safety Data Sheet included with the bath fluid
for more details.)
