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. Both the target temperature and the actual temperature of the bath are displayed continuously on a liquid crystal display. 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.
