Cannon TE-3000

Constant Temperature Bath

Temperature range from –30°C to +30°C Self-contained thermoelectric cooling — no accessory units required Convenient keypad data entry Selectable temperature scale (Celsius or Fahrenheit) Meets ASTM D 445 requirements for temperature stability Built-in platinum resistance thermometer Works well below ambient temperature.

The CANNON TE-3000 Thermoelectric Constant Temperature Bath provides accurate temperature control between –30°C and +30°C, meeting the requirements of ASTM D 445 for measurement of kinematic viscosity at low temperatures.

The low temperatures are obtained by built-in air-cooled Peltier cells which provide thermoelectric cooling. No external refrigeration unit or air/water heat exchanger is used.

Keypad Operation

The desired bath temperature and calibration temperatures are entered digitally by means of a keypad located on the front panel. Temperatures remain in memory even if power to the bath is accidentally cut off. The built-in platinum resistance thermometer continuously monitors the bath temperature and displays it digitally, along with the target temperature, on a back-lit liquid crystal screen. An on-screen menu permits selection of Celsius or Fahrenheit operation, along with several diagnostic features.

Durable Construction

The top cover of the bath contains two round holes 51 mm (2 inches) in diameter for insertion of glass capillary viscometers or other instruments. An additional hole is provided for a reference thermometer or probe. A four-pane “frost-free” viewing window and internal illumination by fluorescent lamps provide excellent visibility within the bath.

The bath holds 2.5 liters (0.66 gal) of bath medium (not supplied). The bath housing is fabricated from heavy aluminum coated with a corrosion-resistant epoxy finish. Contained in the housing is an aluminum bath vessel that measures 305 mm high x 121 mm wide x 83 mm deep. A baffle within the bath vessel facilitates circulation of the liquid and provides a smooth background for viewing instruments.

Viscometers, holders, appropriate bath medium, and thermometers must be purchased separately.
