The measurement techniques of phase transitions in nanoporous media are presented. Along with thermal measurements it is offered to measure electric potentials and power of the microwave radiation propagated through the studied specimens. Microwave radiations are sensitive to phase transition of water-ice because of essential distinction of electromagnetic losses in liquid and ice. When using electrodes from chemically identical metals, electric potentials allow us to define inhomogeneities in the media and transitions through a percolation point. Jump of potentials corresponds to disappearance of through conduction of the media. Examples of effectiveness of the offered techniques at temperature measurements of the wet nanoporous specimens are presented. If three techniques are used simultaneously, it is possible to obtain rather complete information on phase transitions of water in various natural and artificial media.
