Purpose: The device is intended for express diagnostics of type and admixtures in water-alcohol drinks with large content of alcohol and it can be used in manufactories on the vodka-cognac drinks production, in sanitary control services, on a custom.

Description: A type and quality of water-alcohol solutions is explored by the method of dielectric spectroscopy through measuring of frequency characteristics of components of complex conductivity of solution. The device works on principle of impedance spectrometer and provides measuring of total impedance and phase change of the analyzed solution in the frequency range of 5 Hz to 150 kHz through digital filtration (discrete Fourier transformation). Obtained values of active and reactive components of solution resistance have been recounted in parameters of dielectric permeability and their relation.

Basic technical characteristics:
-    range of work frequencies – 0.5 Hz ÷ 150 кHz with step of 1 Hz;
-    maximally possible rejection of fundamental frequency – ±1 %;
-    maximally permissible error of determination of active and reactive constituents of impedance - ±20 % for minimum frequency,  ±10 % for maximum frequency;
-    connecting of sample block through coaxial cables;
-    connection with PC by interface RS232 or USB;
-    voltage supply – constant ±12 V or ±9 V;
-    maximal consumable current – 0.5 А;
-    size – 300х300х70 mm;
-    weight – no more 0.5 kg.
Advantages of device compared to existent analogues are the original method and algorithm of measuring and analysis, portability and small price.
