In cleanroom and particle detection tasks, it is often necessary to dilute high-concentration aerosol particles while maintaining the particle size distribution before and after dilution.
Using an aerosol diluter, the same measurement device can measure both high and low particle concentrations.The instrument uses finely processed capillaries to collect a portion of the aerosol particles, maintaining a constant internal flow ratio. The remaining aerosol is filtered through a HEPA filter via a bypass, and then the two streams are evenly mixed, diluting the particle concentration as it passes through the diluter.
By maintaining a specific ratio between the capillary and bypass, a fixed dilution ratio can be achieved.
