CT500/518 Constant Temperature Viscosity Bath - P4439-1

Description

The Cannon CT-500/518 baths maintain accurate temperature control of ± 0.01°C within the range of 20°C to 100°C, providing the temperature sensitivity required by ASTM D 445 for kinematic viscosity measurements with glass capillary viscometers. Two electric heating elements inside the bath rapidly heat the medium to any desired temperature within the range. A cooling coil, when connected to tap water or a cooling system, permits operation below or slightly above ambient temperature. A special selector switch on the front panel facilitates rapid setting of ten popular temperatures for kinematic viscosity determinations. Temperatures which may be selected with this switch are 20, 25, 30, 40, 50, 60, 70, 80, 90, and 100°C. After the switch has been set, the bath will equilibrate to within a fraction of one degree of the desired temperature. A fine tuning control then allows temperature adjustment to within ± 0.01°C of the target temperature. By switching to the "variable" setting on the front panel, any temperature within the operating range can be obtained. Use the CBC-100 bath cooler to control temperature down to 15 degrees Celsius below room temperature. A solid-state control circuit provides proportional control of temperature. The sensing element for the control circuit is a stainless steel-encased thermistor. A motor-driven stirrer ensures a uniform temperature throughout the bath. The entire electrical control system is located in a convenient drawer, mounted on glides for easy access if adjustment or repair is necessary. The CT-500 bath chamber is a cylindrical clear glass vessel 305 mm (12 inches) in diameter and 305 mm (12 inches) high. The CT-518 bath chamber is a full 457 mm (18 inches) high. A PTFE®-coated stainless steel baffle located in the center of the bath provides a plain reflective background to aid in viewing instruments. The top cover contains seven round holes 51 mm (2 inches) in diameter for insertion of viscometer holders, allowing up to seven viscosity measurements to be made simultaneously. Covers are supplied for capping unused holes. Two additional holes 10 mm (3/8-inch) in diameter are provided for thermometers. Other hole configurations are available on special order. All wetted parts of the CT-500/518 Constant Temperature Baths are made of stainless steel, glass, or PTFE. The frame is fabricated from heavy aluminum and coated with a corrosion-resistant epoxy finish. Viscometers, holders, bath oil, and thermometers must be purchased separately.
