Introduction/Installation
This manual is intended to provide information on the installation, characteristics and operation of
the CANNON CT-500/600 series II Constant Temperature 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
Effective Temperature Range
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 CT- 500 system meets the
sensitivity requirements of ASTM D445.
Temperature Selection
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.

Bath Description
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 steel- encased thermistor. The entire electrical control system is
located in a drawer beneath the bath.
