In addition to the legal re��uirements of an annual device cali��ration, on-site quality checks of critical components such as the dilution system and the particle number counter are highly recommended. Apart from particle num��er checks, there is also a demand for on-site verifi cation of other particle measurement devices. Those re��uirements necessitate a particle generator with: • Adjustable dilution over a wide dilution range • Adjustable particle sizes FUNCTIONAL PRINCIPLE The AVL Particle ��enerator is a stand-alone device for generating a pre-conditioned com��ustion aerosol. Aerosol particles are fi rst formed during com��ustion of propane and then pre-treated and diluted in an integrated Volatile Particle Remover system. The pre-treatment process sta��ilizes particle size and num��er concentration while ensuring reduction of volatile and semi-volatile particles. A further dilution stage with a dilution bridge can decrease the concentration to very low levels. The three dilution stages etrations and size distri��utions. An integrated touch-screen display and four pre-adjusted operating points ensure straightfor- ward and fast operation. The pre-adjusted operating points and the recommended applications are based on many years of AVL e��pertise in the fi eld of particulate measurements. APPLICATIONS �� On-site ��uality checks of particle counting devices – Particle Concentration Reduction Factor check – Particle Num��er Counter linearity check – Particle Num��er Counter cut-off check • Comparison measurement of Micro Soot Sensors and PM-PEMS devices BENEFITS AT A GLANCE • Generation of a highly stable combustion aerosol �� Wide range of applications due to integrated dilution stages �� Cali��rated operating points for a convenient verifi cation of particle measurement devices �� Straightforward on-site ��uality checks of particle measurement devices �� Utilization as stand-alone device �� Integrated touch-screen for simplifi ed operation
