INNOVATIONS IN VISCOSITY MEASUREMENTCANNON ® <strong>CT</strong>-<strong>2000</strong>Constant Temperature Bath• Microprocessor-Controlled TemperatureRegulation to 150°C• Built-in Platinum Resistance Thermometer• On-Screen Temperature MonitoringThe CANNON <strong>CT</strong>-<strong>2000</strong> Constant Temperature Bath maintains the accurate controlrequired by ASTM D445 for kinematic viscosity measurements. Within the range of 20 to100°C temperature is controlled to 0.01°C; outside that range, temperature stability iscontrolled to within ± 0.03°C.Setting TemperatureA front panel keypad permits convenient temperature selection to two decimal places at anytemperature from +10°C to 150°C.The built-in platinum resistance thermometer continuously monitors bath temperature anddisplays it digitally on a four line by twenty character back-lit liquid-crystal screen. EitherCelsius or Fahrenheit display of temperature may be selected. On power-up, the <strong>CT</strong>-<strong>2000</strong>performs an automatic self-test of its circuits.The <strong>CT</strong>-<strong>2000</strong> also features RS-232 and RS-485 communication ports which permit dataacquisition and networking via an external computer. Several baths may be networked to asingle computer.Bath FeaturesThe bath chamber is a cylindrical clear vessel 300 mm (12 inches) in diameter x 300 mm (12 inches) high. A stainless steel baffle is located inthe center of the bath to provide a good background for viewing viscometers. Two fluorescent lamps illuminate the interior of the bath brightlyand uniformly, without glare.Twin heating elements inside the bath rapidly heat the medium to any desired temperature within the range. A cooling coil, when connectedto tap water or a cooling system, permits operation near ambient temperature. The cooling coil or an accessory cooling unit (CBC-100) isrequired for bath operation below ambient.The top cover contains seven round holes 51 mm (2 inches) in diameter. Up to seven glass capillary viscometers (in holders) can be placed inthe bath. Two additional holes 10 mm (p-inch) in diameter are provided for thermometers.A solid-state control circuit equipped with a stainless steel-encased thermistor provides proportional control of temperature. A motor drivenstirrer ensures a uniform temperature throughout the bath. The entire electrical control system is located in a convenient drawer for easy accessif adjustment or repair is necessary.All wetted parts of the bath are made of stainless steel or glass. The bath housing is fabricated from heavy aluminum and coated with acorrosion-resistant epoxy finish. The top cover consists of three parts: a stainless steel top surface, an insulating layer, and a bottom stainlesssteel heat reflector.The bath is designed to use water or oil (not supplied). Viscometers, holders, bath oil and thermometers must be purchased separately.Safety FeaturesThere are multiple safety features. A thermistor in the bath senses any over-temperature fault condition. If such a condition occurs, all poweris removed from the bath until an operator resets the over-temperature limit control circuit. A second safety feature cuts power to the heatersif the control thermistor is disconnected. A liquid-level sensor prevents the control circuit from heating the bath until the safe operating level isattained. The bath heaters are automatically turned off when the bath liquid drops below the minimum safe level.<strong>CT</strong>-<strong>2000</strong> Constant Temperature Bath SpecificationsSize:Bath Volume:Weight:Shipping Weight:Electrical:438 mm wide x 464 mm deep x 584 mm high(17.3 x 18.3 x 23 inches)17 liters (4.5 gallons)51.4 kg (113 lbs) without bath fluid60 kg (131 lbs) (total/two boxes)Specify exact line voltage when orderingOrder InformationCatalog # Item Description9726-A30 <strong>CT</strong>-<strong>2000</strong>, 100-130 VAC, 50/60 Hz, 1400 watts9726-A35 <strong>CT</strong>-<strong>2000</strong>F, 200-250 VAC, 50/60 Hz, 1400 watts2139 High Tech Road • State College • PA • 16803800-676-6232 • 814-353-8000 • Fax 814-353-8007email: cannon@cannoninstrument.com • www.cannoninstrument.com©2012 CANNON <strong>Instrument</strong> <strong>Company</strong> • Printed in USA
