Pegasor Particle Counter

Easy to install
Fast and reliable testing

The measurement is done at idle in less than 30 seconds without the need for free acceleration.

Low maintenance

The straight-through design keeps the sensor clean for extended operating time.

Extended Diffusion Charging
Reliability and high sensitivity

ExTDC consists in electrically charging the particles by the diffusion of a high density of ions (positive) created in a ionization chamber by corona effect.

The concentration of charged particles is measured when leaving the sensor, the measurement corresponding to a leakage current per unit of time. This leakage current is proportional to the number of particles (and their specific surface) leaving the sensor per second, it allows to easily find the concentration in number and even in mass of particles.
