A set for measuring sound levels, infrasound, ultra-sound and vibration, measuring microclimatic parameters of the air environment (temperature, humidity, pressure, air velocity), as well as measuring illumination, brightness and pulsation coefficient.

PARMA TENSOR-2 (AC bridge) is designed for automatic measurements of: · capacitance and tangent of the dielectric loss angle of high-voltage insulation of capacitors, inputs, transformers using an external high-voltage capacitor, both in laboratory and in the "field" conditions · effective values of the first harmonic of the current and voltage of the industrial frequency · the angle of phase shift between the signals supplied to the inputs of the device · network frequencies * Measurements can be carried out according to the "straight" and "inverse" (inverted) scheme. * Allocates the vector of the influence current, which makes it possible to dispense with the phase regulator of the test voltage source or devices for compensating the influence current.

The three-component electric and magnetic field parameter meter is designed to monitor electromagnetic safety standards for special assessment of working conditions, production control and comprehensive sanitary and hygienic inspections of facilities. The meter is equipped with isotropic EMF (non-directional reception) sensors.

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 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
