Temperature selection
The CT-2000 offers convenient keypad entry of temperature settings up
to three decimal places over the entire temperature range of the instru-
ment. The bath temperature will remain stable within hundredths of one
degree of the temperature setting.
Temperature stability
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 or closer. (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 in 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. Twin fluorescent lamps provide glare-free illumination of
the bath.
Microprocessor circuitry, functioning in tandem with a pair of heaters
and a stainless steel-encased RTD provides stable and accurate tempera-
ture 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.
ASTM D 445 specifications
The CT-2000 temperature control provides the accuracy required by
ASTM D 445 for kinematic viscosity measurements.
Cooling coil
A built-in cooling coil, when connected to tap water or a cooling system,
permits operation to 10° Celsius.
