PM Measurement: InSitu Methods

Pegasor Particle Sensor. Another diffusion charging based system is the Pegasor Particle Sensor (PPS) [3427]. This sensor contains no sizing section, the calibration in number concentration therefore depends on the particle size distribution. To overcome this, it was suggested to use two sensors with different tuning [3428]. The ratio of the ...
