The indicator of electromagnetic fields of industrial frequency VE-50I is designed to measure the effective values of magnetic field induction (elliptically polarized) and electric field strength of industrial frequency 50 Hz. It is used to control the electromagnetic safety of industrial electrical installations during a comprehensive sanitary and hygienic inspection of residential and industrial premises and workplaces

Purpose: The device is designed to monitor compliance with the maximum permissible levels of high-frequency radiation (alternating electric field strength, alternating magnetic field strength and electromagnetic field energy flux density) at the workplaces of personnel servicing electrical and radio engineering installations and systems emitting an electromagnetic field, in accordance with GOST 12.1.006, GN 2.1.8./2.2.4.019 and San-PiN 2.2.4/2.1.8.055.

The measuring converter of the Earth's magnetic field is made on the basis of magnetoresistive sensors that simultaneously measure the orthogonal components of the magnetic field strength at the control point and the modulus of the intensity vector. At the same time, the magnetometer readings do not depend on the orientation of the measuring transducer in space. The MTM-01 magnetometer is also an effective means of measuring the quality of magnetic protections and screens to ensure the standards of electromagnetic safety of workers and the public during the operation of distribution transformers and electric power plants.

The companies NTM-Zashchita LLC (Moscow) and Avtospectr-NN (Nizhny Novgorod) have implemented a joint project "Mobile Laboratory for Physical Factors Control", which is a mobile complex equipped with the most modern equipment of well-known Russian and foreign manufacturers, designed to effectively solve the problems of sanitary and hygienic control and labor protection, certification of workplaces and monitoring of the production environment.

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

Designed for storing and transmitting the size of a resistance unit, as well as for checking and calibration of working resistance measures and complex resistance meters with a four-pair or five-clamp connection scheme in the frequency range from DC to 10 MHz.
