product sheet DIL 500 seriesBenefits
- dilution ratio is automatically adjusted
- mobile use (no compressed air supply is required, battery operation possible)
- directing the entire intake volume flow of the particle counter from the sampling point via the dilution system (closed system)
- constant, reproducible dilution even under changing operating conditions
- internal monitoring of the dilution ratio with display
- high durability and reliability, minimum maintenance
- over- and under-pressure operation is permitted
- adaptation to customer-specific requirements (dilution ratios) possible
- can be operated in connection of series
A partial stream is extracted from the raw aerosol flow. The particle concentration in the partial flow (capillary volume flow) will remain unchanged. A HEPA filter is used for separation of particles from the by-pass flow. The two flows are recombined. Dilution results from the ratio of the total flow to the capillary volume flow.
The fluidic design of the device ensures isokinetic sampling at the inlet of the capillary. Interferences of particle size distribution of the aerosol through diluting are therefore minimal.
Optical particle counters have inherently a maximum measurable particle concentration. If this is exceeded, errors are to be expected for reasons of coincidence in the measurement volume of the counter. By placing the dilution system DIL 54X upstream of the particle counter, the aerosol concentration can be reduced by a factor of 10.
