DIL 544 Dilution System
DIL 544 Dilution System for static dilution (1:100) of aerosols at static air flow rate (28,3 L/min) for mobile operation
Standards
Both DIL 544 and DIL 554 are connected directly to a cleanroom particle counter via a hose. Therefore, the sampling volume flow is generated by the cleanroom counter. Inside the dilution systems, the aerosol sample is divided into two partial volume\r\nflows. From one partial volume flow (bypass), all particles are removed using a HEPA filter. Subsequently, both volume flows are recombined, whereby the particle number concentration at the outlet of the dilution system is reduced.
