FIELD: the invention refers to physical express diagnostics of liquids.
SUBSTANCE: identification and control of liquids quality is carried out according to individual features of the process of development and relaxation of thermal capillary response under review in the beam of a reading laser reflected from liquid surface. The functions of inducing laser fulfills a source of thermal impulses on the basis of Peltier's element which can influence on liquid both as with local increasing, so by decreasing temperature.
EFFECT: simplifies the process of control of parameters inducing convection of influences and expands regimes of influencing on liquid.
