Silicone hose with an inner diameter of 8 mm is used to connect circulation coolers A160 and A300 with thermostats of the W series or to external consumers.

Vibration velocity sensors with a current output DVST-2 are designed to convert the RMS value of the vibration velocity of an object into a standard current signal of 4-20 mA.

It is used in the study of samples compressed into small-diameter tablets with KBr (the method is convenient for spectral analysis of powdery substances - the prefix allows you to work with small amounts of the sample using a manual press for the manufacture of tablets). • The diameter of the focus spot is less than 3 mm • Parabolic mirror optics are used in the design • Windows-substrates can be placed in the prefix after pasty, liquid substances or extracts are applied to them, followed by drying of the layers • Limited use – in the study of whole samples with dimensions less than 5 mm (preferably using a vertical-type microfocusing attachment)

The set of devices is designed to install five working viscometers in a vertical position in the bath of the VIS T 06 liquid thermostat when they are verified.

It is intended for express analysis of various types of solid and liquid samples, including polymer particles, films and fibers, powdery substances, fragments of paint coatings, fuels and lubricants. The presence of an optical system for visual inspection of the surface under study with an increase of 75X ensures high efficiency when working with small samples – fragments of thin fibers, microparticles, etc. The universal clamp is equipped with a precision lever mechanism for quickly lowering the tip and a micrometer screw that allows you to pre–set the optimal degree of pressure - this ensures quick sample change and repeatability of the results during measurements. For convenience when working with liquid and paste-like samples, as well as in the ZDO mode, it is possible to rotate the clamping console by 180o. The console is equipped with two replaceable tips – with a spherical working part and with a flat hinged head. A replacement table is used to register the specular and diffuse reflection spectra. The sample is located on the subject plane of the investigated surface downwards, the angle of incidence of the central beam on the sample is 45 °. The method is used to determine the spectral characteristics of optical parts, crystals, thin films on the surface, as well as to register the absorption spectra of large solid objects. Transmission in the operating range of the spectrum, % of the input signal at least 30 The recommended number of scans when registering spectra is 25 Spectrum registration time at 25 scans (resolution 4 cm-1), sec 30 The depth of penetration of radiation into the sample, microns 5 – 15 Minimum area of a solid sample, mm 0.2 × 0.2 Minimum volume of the liquid under study, ml 1 Minimum dimensions of the fiber sample: cross-section diameter/length, mm 0.1/1 Substrate crystal material ZnSe CVD, Ge Focusing spot diameter, mm 1 The angle of incidence of radiation (central beam) on the sample in the ZDO mode 45o Magnification of the micro lens / total magnification of the visual channel 4X /75X Field of view of the optical system, mm 2 X 2.5 Digital video camera resolution 640 X 480 Overall dimensions, mm 150×150×260 Weight, kg 2.15 • Allows you to study objects of small size (from 200 microns - depending on the geometry, surface quality and physico-chemical properties of the material) • The attachment allows you to work without sample preparation, has a fixed adjustment of the pressure on the sample using a clamp equipped with color indicators • Thanks to the removable flange with the NPVO element, a quick and convenient sample change and cleaning of the crystal surface is provided • At a given optimal contact force, the method provides high quality and repeatability of results due to the absence of influence of the thickness of the substance layer on the shape of the spectrum and the intensity of the absorption bands • The sample retains its original physical and chemical properties and, if necessary, can be further investigated by other methods

KOIDZ-VD kits consist of samples of artificial defects (SAD) and samples of gaps (SG). Samples of artificial defects are made in the form of flat and curved plates and cylinders, on the working surfaces of which defects are made in the form of continuity violations like slits of various depths, opening widths and lengths. The working surfaces of flat SADs are two opposite surfaces on which longitudinal slits are cut by an electroerosion method The working surfaces of the SAD, reproducing a positive curved surface, are samples with a cylindrical surface. The working surface of the SAD reproducing negative curvature is the inner surface of the curved plate — the place of inflection. The KOIDZ-VD kit contains an SAD for determining the influence of various quantities. To determine the effect of the roughness of the working surfaces, the kit contains SADs with different roughness, on which defects of the same depth are made. To determine the effect of positive curvature and surface roughness, the kit contains cylindrical samples with different roughness of working surfaces on which defects of the same depth are made. To determine the simultaneous effect of negative curvature and surface roughness, the kit contains curved plates on which two defects of the same depth are cut, one of which is located on the flat, the other on the curved parts of the sample. To determine the effect of the chemical composition of the material of the controlled products, the kit contains samples of steel 10, steel 20 and steel 45. The same defects are made on each sample. To account for the influence of specific electrical conductivity, the kit contains samples from non-magnetic structural materials: aluminum alloy D16T and titanium alloy VT-23. The same defects are made on each sample. Gap samples are flat and curved plates of different thicknesses made of dielectric material.
