The capillary methods are widely applied to control products made of non-magnetic, non-metallic, composite and other advanced materials, and in most cases these methods are considered to be the only available techniques. The article considers options for manufacturing non metallic check samples for penetrant testing in terms of several cracks performed on one and the same sample and corresponding to different classes of sensitivity. The basis was a non-metallic material, an epoxy adhesive, and the defects were made by etching foil. Such samples are easy to manufacture, the defects performed are of desired parameters. This increases the actual output of the final product, the material is not exposed to corrosion, and the quality of sample cleaning increases as they are practically transparent.

The summary of thermocatalytic sensors development is presented. The questions connected with instability of sensors while in operation are considered. It is suggested with the aim of stability increase to use a limited access of analyte into the reaction chamber keeping particular conditions. The analysis of diffusion processes is carried out; recommendations on increase of measurements stability by several times are given.

The diagram of a microwave radiometer on the basis of modification of a method of zero measurements with the high response characteristics which distinctive feature is use of one noise generator for formation of two calibrating quantities is described. It reduces an error of measurements from change of power output of a generating element and simplifies calibration process for radiometer setup on the given measurement range.

The methods of the free-field realization at measurements in the pool with reflecting boundaries are considered. It is shown that the separation of these methods on themethodof measurement in a free field "by definition" and recalculation to a free field conditions is unfounded. The possibility to estimate the quality of free field conditions at calibration of acoustic receiver by the width of frequency band blurring and the time of reflections delay in the signal receiving point - has been shown.

The specialized g-spectrometry installations complex is considered and the metrological characteristics of the instrument spectrum has been studied on real ionizing sources.

This article describes an approach to the measurement of the blood cell nuclei structural elements parameters used for recognition of blast cells in images of hematologic microscope mounts. The model for the description of optical characteristics of the blood cells nuclei is proposed. The model is based on qualitative characteristics used by physicians of clinical laboratory diagnostics for microscopic analysis of blood smears.
