The principle of operation of dosimeters is based on the accumulation of ionizing radiation energy by detectors proportional to the radiation dose. In DVG-02TM installations, DOZA-TLD complexes, etc., when the detector is heated, the accumulated energy is released in the form of light radiation, which is recorded by an electronic device.

Installation for verification and calibration of individual beta radiation dosimeters. Properties The unit transmits units of absorbed dose (PD) and absorbed dose rate (MPD) of beta radiation in a tissue equivalent substance at a depth corresponding to a surface density of 7 mg•cm-2; the transition to units of the individual equivalent of the Hp dose (0.07) in sieverts from units of beta radiation absorbed in the tissue in gray is carried out using conversion coefficients recommended by the international standard ISO 6980-3:2006; the installation can be used in metrological bodies for verification of individual beta radiation dosimeters such as DMC 2000 XB, EPD Mk2 and others.

14 high-precision stepper motors control all moving parts of the microscope, and intelligent software blurs the line between optical and SPM imaging. NEXT provides continuous magnification from millimeter-scale panoramic optical images to atomic resolution, and intermediate operations such as laser pointing to the cantilever, sample positioning, soft approach and configuration of advanced SPM techniques occur automatically.

It is indispensable when used by the services of Rospotrebnadzor and labor protection to control the parameters of the microclimate, certification of workplaces at industrial enterprises, offices and public institutions.

Meets the requirements of the US and German standards. The energy flux density meter (PPE) of the electromagnetic field PZ-ZZM is designed to measure the PPE in continuous generation mode in the frequency range from 0.3 to 18 GHz when monitoring the levels of the electromagnetic field for compliance with the requirements of electromagnetic safety standards. The meter is used to measure the levels of microwave radiation in residential and working premises in the presence of electrical equipment for power, household, switching and information purposes, as well as during a comprehensive sanitary and hygienic survey of territories. The meter is allowed to be used for work in the field. The meter consists of an antenna-converter of the electromagnetic field energy flux density into a constant voltage and a measuring and display unit that performs analog-to-digital conversion, digital signal processing and output of measurement results to a liquid crystal display screen, as well as to a personal computer. The antenna of the meter has three dipole-detector microassemblies that form a mutually orthogonal structure. The resulting PPE value is defined as the vector sum of the PPE measured by each dipole microassembly

The complex is equipped with air conditioning, heating and ventilation systems to create and maintain a preset temperature level (20 ...25) ° C in the van body, at an outdoor temperature from minus 40 ° C to 40 ° C. PLIT-A2-4/1M is equipped with a removable diesel electric unit with a capacity of 16 kW, which ensures the functioning of all systems in autonomous mode. A set of functionally related working standards, special equipment and automation tools allows you to implement comprehensive metrological maintenance of measuring instruments at workplaces

Vascular Endothelial Growth Factor is one of the key regulators of angiogenesis. The most important role in the human body is played by a protein of the VEGF family called VEGF-A. VEGF-A is a 45 kDa glycoprotein homodimer and plays a key role in chemotaxis and angioblast differentiation, endotheliocyte (EC) proliferation, vasculogenesis, and vascular remodeling. As a result of alternative splicing or proteolytic cleavage, 4 main isoforms of VEGF-A are formed, consisting of 121, 165, 189, or 206 amino acid residues.

The FGH-1-2 chromatographs have retained the main advantages of the FGH-1 model – mobility and ease of operation and maintenance. At the same time, FGH-1-2 has all the advantages of a modern multichannel chromatograph – the ability to reliably identify and accurately determine the concentrations of various pollutants of environmental objects. The additional use of automatic identification in the processing of chromatograms simultaneously through both channels makes FGH-1-2, in fact, a universal selective gas analyzer of organic substances using the chromatographic separation method. In FGH-1-2, as well as in FGH-1, all methodological problems have been solved: all measurement methods (MI) used are certified, the devices are equipped with sampling devices prescribed in MI, the devices are graded according to the required substances, independent control of the stability of calibration characteristics and measurement errors is provided.
