Calibrating system of particle counter
2015
The invention discloses a calibrating system of particle counter. The calibrating system is used to calibrate particle counters. The connection relationships are as follows: compressed air is introduced into the input channel of an aerosol generator, the aerosol generator is connected to a diffusion drying pipe through a pipeline, compressed air is introduced into the pipeline between the aerosol generator and the diffusion drying pipe, the diffusion drying pipe is connected to a static electricity neutralizer through a pipeline, which is connected to external atmosphere and is used to discharge excess gas; the static electricity neutralizer is connected to a particle size spectrometer through a pipeline, the particle size spectrometer is connected to a mixing box through a pipeline, compressed air is introduced into the pipeline between the particle size spectrometer and the mixing box; the mixing box is connected to a shunt, one output channel of the shunt is connected to a particle counter FCE through a pipeline, the other output channel of the shunt is connected to the input channel of a diluter through a pipeline, wherein the diluter has two input channels, the other input channel of the diluter is used to receive compressed air, and the output channel is connected to a non-calibrated particle counter CPC through a pipeline.
