Introduction of electronic semiconductor liquid particle counter
Electronic semiconductor liquid particle electronic counter can be used for cleaning agents, semiconductors, ultra-pure water, electronic products, cell phone glass, flat glass, silicon wafers and other products on-line particle monitoring and analysis, is currently the British Plodi analysis and testing group to the quality of the field of micro-nano-combined detection of the important products.
Laser particle counter and laser dust meter (PM2.5 dust detection
Dust particle counter (laser particle counter) and (Laser dust meter) PM2.5 dust Detector is the principle of laser scattering method for particulate matter detection equipment, but the application of the two fields are different. Dust particle counter is used in cleanroom, clean room to detect cleanliness level.
Competition pattern and development trend of instrument automation industry in recent years
In recent years, a large number of new enterprises into the instruments and meters low-end product market, from the scale and cost of the original leading enterprise products shocks, domestic well-known instrumentation manufacturers in the introduction of technology development, optimize the capital structure, expand business scope, as well as increase cooperation with well-known foreign companies have been strengthened, the market competition is more intense,
