Brief introduction The instrument uses the principle of beta ray absorption weighing, to capture the PM2.5 or PM10 particles on the filter membrane for automatic and accurate measurement, automatic continuous monitoring of the concentration of PM2.5 and PM10. The instrument has the advantages of small volume, convenient installation, with dustproof and rainproof characteristics, it can automatic work in the outdoors for a long time. The instrument is in accordance with the relevant provisions of HJ653-2013 and GB3095-2012, and it is widely used in environmental monitoring, environmental assessment, scientific research, emergency monitoring and environmental air monitoring station data. Features The principle of advanced beta ray absorption weighing +DHS (dynamic heating system) is used to directly measure the particle mass concentration, which is not affected by the physical and chemical properties of the particles. The impact of no correction, all-weather real-time to provide accurate data; With the dynamic temperature and humidity compensation function, in line with national standards, can guarantee the semi - volatile nitrate and organic compounds of the precise measurement; Real time measuring and matching different cutter PM10 and PM2.5 concentration; Using low activity C14 beta source, safe and reliable; Adopt wide temperature type industrial touch screen, easy to operate; The air inlet pipe is heated by a heating device, and an air sampling air is automatically carried out according to the set humidity value; Automatic measurement of temperature and humidity and air pressure and other parameters, and automatic conversion of standard state sampling volume; The instrument can automatically store the historical data, can be printed on the spot or exported by U disk; With digital and analog output interface, can be easily connected to the number of network transmission; With the wireless communication module, remote query instrument working state and real-time measurement data; Instrument with power cut automatically save the current data, when the call after the instrument can be maintained to continue sampling; Instrument has the independent broken belt, the filter paper is exhausted as well as the mechanical breakdown test procedure; Problems instrument automatic alarm, and equipment protection; Good portability, quick and direct installation, continuous and automatic operation, which can be applied to many kinds of test applications; Optional with wind direction and wind speed sensor, automatic heating and data recording function.
