        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. |
