The paper describes an in house made experimental set-up that
measures the thermal conductivity of liquids. The measurement principle is
based on the Transient Hot Wire Method. The theoretical bases of the mea-
surement method are ¯rstly presented, and then our original experimental im-
plementation is described. The hardware as well as the software design reveals
the simple con¯guration of the measurement set-up that contains high perfor-
mance inexpensive components. It is also simple to use and well suited for
research laboratories, data being stored either in text, or in graphical ¯les. Fi-
nally, based on experimental results, the measurement accuracy and sensibility
performances are discussed and compared with other instruments in literature.
