Importance of control of mental states and mental intensity on professional activity of the person is noted and methods of increase of efficiency of decision-making are offered. It is offered as a source of information on mental intensity to use parameters of haemodynamics and the skin and galvanic reaction (SGR) of the examinee. The device is developed for an assessment of adaptive opportunities and control of conditions of the person, representing multiparameter system in which to each parameter there correspond one or several measuring channels. The block diagram of the developed device is provided in article and the algorithm allowing in the course of measurements to carry out two modes is realized: mode of adaptation of channels and data collection mode. It is established that use of the offered device allows to control a functional condition of the main regulatory systems of the person, and each of systems is described by the complex of "slow waves". It is noted that operation of the device is based on synchronous record of a signal of the photoplethysmogram and KGR. The microconverter which realizes negative feedback is entered into the device and carries out synchronization of record of the signals arriving from different channels.
