The laser dust meter is a pocket type dust meter with a laser as the light source. It can quickly detect dust. Most of the laser dust instruments on the market can meet the industry standards of the Ministry of Health and are widely used throughout the country. The laser dust meter is suitable for the rapid determination of the concentration of PM10 in public places, the detection of dust concentrations in the labor and mining enterprises on the production site, and the monitoring of the concentration of inhalable dust in the environmental protection field. It can also be used for the purification efficiency of air purifiers. evaluation of.
Compared with foreign laser dust instrument technology, the detection technology of domestic dust instrument equipment is not mature enough. Therefore, most dust instrument equipment manufacturers on the market have introduced a full set of manufacturing and inspection calibration technologies and equipment from Japan or other countries, achieving new built-in technologies. The micro-computer laser dust measurer of the filter membrane on-line sampler can continuously collect particulate matter samples while monitoring the dust mass concentration, and achieves a variety of cutter switching, which can temporarily meet the demand for dust detection in China.
Industry experts said that China's dust instruments and equipment industry usher in a good opportunity for development, but in order to long-term and stable development, we must have to rely on imported technology, imported equipment, and break the homogenization of products, absorbing foreign references At the same time, the brand, technology, and achieve independent innovation, so that the equipment can be used locally to better serve our country's dust testing.
With the development of automation and domestic dust detection technology, domestic laser dust instruments have been able to achieve online detection capabilities. On-line monitoring equipment can continuously monitor dust emissions from pollution sources in wind, rain, lightning, dust, high and low temperatures and other harsh environments for a long period of time. At present, online laser dust instruments have been widely used in the monitoring of soot emissions from environmental pollution sources, the monitoring of the efficiency of dust removal equipment, the monitoring of combustion efficiency, the measurement of dust concentration in industrial manufacturing processes, the monitoring of occupational health protection dust in industrial and mining enterprises, and the dust load monitoring in production plants and factories. Scientific research, experimental field testing, etc., involve a variety of industries.
In recent years, while energy-saving and environmental protection concepts have become the trend of the times, the requirements for environmental testing equipment in all walks of life are constantly increasing. As a device for dust detection, the dust meter manufacturers must also stand at the outlet of market demand, improve the internal technology and independent innovation, establish a brand image for the outside world, and stand ready to meet new challenges at any time.
