        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. |
