The Model 3034 Scanning Mobility Particle Sizer™ (SMPS™) spectrometer measures aerosol particles in the range from 10 to 487 nm. It displays data using 54 size channels (32 channels per decade) for high-resolution size information.
This submicrometer particle sizer is capable of measuring concentrations in the range from 1 to 2.4 x 106 particles/cm3. Therefore, it is well-suited for applications with both low and high particle concentrations. Like our component SMPS spectrometers, the Model 3034 uses the same continuous, fast-scanning technique to avoid gaps in the particle-size-distribution data. It differs in that it has a CPC, DMA, all flow controls, and fixed operating parameters integrated in a single cabinet. This greatly simplifies instrument transport, set up, and operation.
The Model 3034 Scanning Mobility Particle Sizer generates a new particle size distribution every three minutes. It can operate for 30 days without a refill, it includes an auto-recovery feature in the event of a power loss, and it uses only 1 Kb of PC memory per scan! Plus, it corrects for ambient pressure and temperature automatically, so there is no need for post-acquisition data manipulation.
The TSI Rotating Disk Thermodiluter is highly regarded in the field of particle emission measurement, especially for sampling, diluting and conditioning exhaust from diesel and spark-ignition engines.
