The analyser consists of a series of electromagnetic field emitters/receivers (40) operating at a number of frequencies over a predetermined range between a few Hz to a few GHz, a holder (22) for a container (R) to be analysed, designed to ensure its precise position relative to the scanning signals from the emitters/receivers, and a measuring system (50) for the complex impedance produced by the container and its contents. The measured impedance is compared with reference values; the measuring system generates an alarm signal when the impedance is outside reference values, and an indicator (7) displays the nature of the contents. |
