Introduction/Installation
This manual is intended to provide information on the installation, characteristics and operation of
the CANNON CT-2000 Constant Temperature Bath.
The CANNON CT-2000 Constant Temperature Bath is designed to maintain precise temperatures at
a wide range of settings for accurate viscosity measurements. Because of its temperature stability
and ease of use, it is also suitable for any other application where temperatures must be maintained
within hundredths of one degree Celsius.
The CANNON CT-2000 is designed to maintain temperatures from 10 °C to 150 °C.
Figure 1: CANNON CT-2000 Extended Range Constant Temperature Bath
Temperature Selection and Selection
The CT-2000 offers convenient keypad entry of temperature settings up to three decimal places over
the entire temperature range of the instrument. The bath temperature will remain stable within one
1/100ths of one degree of the temperature setting.

CT-2000 Instruction Manual
The CANNON CT-2000 is capable of maintaining temperatures of 10 °C to 100 °C within 0.01 °C and
temperatures of 101 °C to 150 °C within 0.03 °C. (Temperature stability at or below ambient may
vary depending on the quality of the external cooling unit.)
Bath Description
The bath chamber is a cylindrical clear 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 within the bath. The top cover
contains seven round holes, 51 mm (two inches) in diameter, for insertion of viscometer holders.
Two smaller holes are provided for thermometers, as shown in Figure 2. Twin fluorescent lamps
provide glare-free illumination of the bath.
Figure 2: CT-2000 Top View of Viscometer Holders
Microprocessor circuitry, functioning in tandem with a pair of heaters and a stainless steel-encased
RTD provides stable and accurate temperature control. A motor-driven stirrer ensures that a
uniform temperature is maintained throughout the bath.
The bath housing is fabricated from heavy aluminum and coated with a corrosion-resistant epoxy.
The top cover consists of three layers: a stainless steel top surface, an insulating layer, and a bottom
stainless steel heat reflector as shown in Figure 3.

Safety Precautions
Always observe cautionary messages, signs and warnings in order to protect yourself as well as
prevent others from physical injury or property damage.
Overheat Thermistor
A thermistor in the bath senses any over-temperature fault condition. If such a condition occurs, all
power is removed from the bath until the operator resets the over-temperature limit circuit.
RTD Cutoff Detection
If the control RTD is disconnected, all power to the bath heaters is cut off.
Liquid-Level Sensor
Bath operation is only possible when it is filled with liquid to a safe operating level. A liquid-level
sensor prevents the control circuit from heating the bath until the safe operating level is attained.
The bath heaters automatically turn off if the bath liquid drops below the minimum safe level.
•Only qualified personnel should operate the CT-2000.
•Place the CT-2000 on a stable surface such as a laboratory table or bench. Do not place
instrument on a cart or stand.
•If any liquids are spilled into the electronic components of the CT- 2000, contact Cannon
Instrument Company immediately.
•Position power cords so they will not be walked on or pinched by items placed on or against
them. Keep all connections as neat as possible.
•Unplug the power cord from the wall outlet if the CT-2000 will not be used for an extended
period of time. Disconnect the power cord by pulling it out by the plug, never pull by the cord.
•Read and understand all operating instructions and safety precautions listed in this manual
before installing or operating the instrument. Any questions regarding instrument operation or
documentation should be referred to Cannon Instrument Company.
•Do not deviate from the installation, operation, or maintenance procedures described in this
manual. Improper use of the CT-2000 may result in a hazardous situation and may void the
manufacturer’s warranty.
•Handle and transport the unit with care. Sudden jolts or impacts may cause damage to
components.
•Never operate the instrument without proper levels of approved bath fluid in bath.
