The testo DiSCmini is the smallest instrument on the market which can measure nanoparticle number. The portable particle counter can be used for recording personal contamination or for fast non-stationary measurements in important environments such as workplaces or city areas with high traffic levels. Previous studies describe the negative impacts of ultra fine particles on health based on vague benchmarks. With the testo DiSCmini, it is now possible to measure the particle number concentration and surface area of occurent nanoparticles, LDSA (Lung Deposited Surface Area). Typical applications of the DiSCmini include the determination of personal exposure in particle-contaminated workplaces (for example due to diesel soot, welding fumes and industrial nanoparticles) or in vulnerable groups (such as asthmatics or COPD patients). In addition to this, the testo DiSCmini offers various application possibilities in different disciplines of scientific research. The small size of the testo DiSCmini makes the instrument particularly suitable for mobile on-site measuring tasks and the set-up of networks for the monitoring of ambient air. Thanks to the measurement rate with a time resolution of 1 Hz for all three measurement parameters, you also identify quick alterations in the aerosol number.
