Abstract
A thermal bridge is employed to compare thermal transfer characteristics of test and reference surfaces immersed in identical fluid environments so as to determine thermal transfer characteristics of the test surface substantially independent of fluid environment. The thermal bridge is balanced, the test surface is caused to be scaled to a greater degree than the reference surface and a comparative measurement is made with the two surfaces exposed to identical fluid environments. The method is performed by a single probe having two or more surfaces that are heated and of which the differential temperatures are monitored. Readings are adjusted to compensate for effects of a varying fluid environment.
