Способ измерения концентрации частиц аэрозоля в реальном времени, состоящий из забора пробы аэрозоля из окружающей среды на техническое устройство, распределения отобранного аэрозоля по дисперсности в соответствующих камерах технического устройства и измерения концентрации аэрозоля в каждой камере, отличающийся тем, что измерения проводятся полупроводниковыми сенсорами по изменению их проводимости после предварительного прогрева, для чего проводится предварительная калибровка сенсоров по их проводимости на атмосферном воздухе и на воздухе, содержащем аэрозоль с известной концентрацией и дисперсностью, которая принимается постоянной вплоть до окончания измерений, причем калибровка осуществляется для каждого сенсора, с учетом калибровки значения проводимостей по заданному алгоритму пересчитываются в концентрации.2. Способ по п.1, отличающийся тем, что калибровку дополнительно проводят по другому известному веществу.3. Устройство, состоящее из импактора с последовательно расположенными измерительными камерами, в которых частицы аэрозоля распределяются согласно диапазонам дисперсности, и в каждой из которых установлены датчики концентрации аэрозоля, отличающееся тем, что датчиками являются полупроводниковые кондуктометрические сенсоры.4. Устройство по п.4, отличающееся тем, что сенсоры установлены в зоне торможения потока.1. A method for measuring the concentration of aerosol particles in real time, consisting of taking an aerosol sample from the environment onto a technical device, distributing the selected aerosol by dispersion in the respective chambers of the technical device, and measuring the concentration of aerosol in each chamber, characterized in that the measurements are carried out by semiconductor sensors using a change in their conductivity after pre-heating, for which a preliminary calibration of the sensors according to their conductivity in atmospheric air and in air containing an aerosol with a known concentration and dispersion, which is assumed constant until the end of the measurements, moreover, calibration is carried out for each sensor, taking into account the calibration, the conductivities according to a given algorithm are recalculated in concentration. 2. The method according to claim 1, characterized in that the calibration is additionally carried out on another known substance. A device consisting of an impactor with successive measuring chambers in which aerosol particles are distributed according to dispersion ranges, and in each of which aerosol concentration sensors are installed, characterized in that the sensors are semiconductor conductometric sensors. 4. The device according to claim 4, characterized in that the sensors are installed in the area of flow inhibition.
