The thermal losses through the chamber walls produce temperature gradient and consequently the dew point is reached in the vicinity of specimens and the vapor starts condensing on the surface of the test samples. The Kesternich test gains on popularity due to the fact that the atmosphere in many industrialized countries is increasingly poluted with this gas. These heat losses result in a temperature gradient between the bottom and the roof of the test chamber which is required to reach the dew point inside the test chamber and consequently the water condensation. The CWC system is the main prerequisite for achieving high reproducibility of test conditions and achieving reliable test results. Moreover, the stainless steel design of the test chamber and the surface heating elements allow high thermal conductivity and very fast heat transfer into the chamber. The water in the bath is heated quickly and evenly resulting in even evaporates acrsoos the whole water surface.
