ABSTRACT
When analyzing worldwide market of impedance spectroscopy instrumentation and comparing it to wide range of possible applications of impedance spectroscopy, it can be noticed that the nowadays portable impedance analyzer do not fulfill the current requirements neither functionally, nor costly nor dimensionally especially in case of test performed directly in the field including multi-point telemetric measurements. This leads to conclusion, that there is a need for miniaturized, low-cost and field-worthy impedance analyzers. Presented in the paper the impedance analyzers answer the existing needs.
