FIELD: measurement equipment.
SUBSTANCE: usage: for detection of analysed substances in physiological liquids. The substance of the invention consists in the fact that the electrochemical system comprises: an electrochemical sensor; a testing measurement instrument made as capable of holding the electrochemical sensor; and a circuit inside the testing measurement instrument, besides, the circuit is made as capable of forming an electric connection with the electrochemical sensor, when this sensor is located in the testing measurement instrument, and is additionally made as capable of detection of the first voltage, indicating that neither electrochemical sensor is located in the testing measurement instrument, the second voltage, differing from the first voltage and indicating that in the testing measurement instrument there is an electrochemical sensor without a sample of a physiological liquid, and the third voltage differing from the first and second voltages and indicating that the electrochemical sensor is located in the testing measurement instrument, and the sample of the physiological liquid is applied onto the electrochemical sensor.
EFFECT: provision of the possibility for quicker and more accurate method of detection, when the sample starts filling the electromechanical sensor, and when electrochemical reaction starts inside the sensor.
