Problems of development the methods of monitoring the quality indices of non-electric nature objects are in the highlight of the paper. The chain of experimental investigations of capacitance primary transducers in terms of their time stability (durability) and manufacturing material efficiency has been undertaken. The nature of frequency dependence of admittance on the temperature and different solution concentrations has been researched. Due to the results of investigations the method of
