The results of the Fujian Institute of Metrology can accurately calibrate the dust particle counter

[China Instruments Network Instrument Development] The dust particle counter is an instrument for measuring the number and size distribution of dust particles per unit volume in a clean environment. Recently, the Research on Dynamic Aerosol Dilution System of the Research Institute of Public Welfare Sciences in Fujian Province undertaken by the Metrology Institute of Fujian Province has passed the acceptance. The research results can meet the calibration requirements for large-flow dust particle counters, reaching domestic standards. Leading level.

The project has developed a dynamic aerosol dilution system with a dilution ratio greater than 1:200 and a maximum gas flow rate of 100 L/min, which has good applicability to particles of different sizes and can be used as “JJF 1190-2008 dust particle counter calibration. The supplement of the specification can meet the calibration requirements for large dust particle counters and condensation particle counters for dust particle counters.

The dust particle counter is an instrument for measuring the number and particle size distribution of dust particles per unit volume in a clean environment. It is widely used in drug testing centers, blood centers, epidemic prevention stations, disease control centers, environmental monitoring, and clean laboratory facilities in various provinces and cities. Cleanliness calibration. The results of this project can provide powerful technical support for the traceability of dust particle counters, and can also effectively improve the measurement level of environmental cleanliness. The particle counter developed from the microscope and went through the microscope, settling tube, settlement meter, centrifugal sedimentation instrument, particle counter, laser air particle counter, and PCS nano laser air particle counter. The laser air particle counter test speed is fast and dynamic. Widely distributed, unaffected by human influence and other advantages, it has become a mainstream product in many industries.
