DiSC mini

The all new DiSCmini is a portable sensor for the measurement of particle number and average diameter, based on the electrical charging of the aerosols. The small size of the DiSCmini handheld makes the instrument particularly suitable for personal carry-on measurement campaigns.
Negative health effects due to nanoparticles appear to correlate particularly well with number concentration or surface. Epidemiological and toxicological studies are still mainly based on total mass, or they use fuzzy proxies like "distance from a busy road" to describe personal exposure, although the health-related effects of particle number concentration are well known. We believe that this contradictory situation is due to the lack of adequate sensors on the market.
