Proper dilution and conditioning of exhaust emissions is essential to obtain accurate particle size distribution and particle number concentration measurements. The Spinning Disc Thermodiluter 379020A is highly regarded in the field of particle emission measurements, especially for sampling and diluting diesel and spark ignition engine exhaust. Moreover, it is used with a wide variety of TSI particle sizers and counters, including Scanning Mobility Particle Sizer Systems, Engine Exhaust Particle Sizers, Condensation Particle Counters, EADs, etc.

Combined with the Rotating Disc Thermodiluter 379020A and the Hot Air Conditioner 379030 and the Solid Particle Number (PN) is an engine exhaust condensation particle counter for concentration measurement that fully complies with the Euro 5 specification.
