Abstract
An apparatus for measuring the conductivity of an electrolyte comprises at least one conductivity cell, e.g., syringe-type conductivity cell and a constant temperature jacket. The syringe-type conductivity cell preferably employed in the apparatus comprises a generally longitudinal, cylindrical wall and two electrode rods which serve to define a volume for testing the conductivity of a sample in the volume. The constant temperature jacket comprises at least one longitudinal chamber for holding a conductivity cell, a temperature sensing device, and a fluid channel which is in fluid communication with a source of constant temperature fluid.
