TESTO REXS Reproducible EXhaust Simulator (Soot Generator)

Aerosol: Soot nano-particles produced in the combustion process

Particle mass produced: From 1.5 g/h at 80 nm particle diameter to 2.5 g/h at 110 nm.

Number concentration of particles: 107–108 particles/cm3

Particle size:

- Monomodal logarithmic distribution with a standard deviation of approx. 1.5 to 1.7 for particle sizes between 30 to 60 nm

- Monomodal distribution with a standard deviation of approx. 1.8 to 1.9 for particle sizes between 60 to 120 nm

Output flow testo aerosol: 300 to 700 IN/min at different particle diameters, approx. 150 IN/min in standby mode

Counter-pressure: Up to 500 mbar over atmospheric pressure

Morphology: Similar to diesel soot
