Nano particle counter meDiSC

Nano Partikelzähler meDiSC
Many aerosol particle counters in the nanometer range are largely, with difficulty, sensitively and expensive. To exclude the DiSC developed around all these criteria. It is the first electrical particle measuring instrument of its kind with the requirement of a robust, portable field measuring instrument in Nanometerbereich.Der DiSC is the modification long of a well-known system, the Diffusionsbatterie or diffusion Charger (DC). The aerosol is electrically charged and led by three following measuring stages. In the first diffusion stage first the very small particles in a set of one behind the other lying high-grade steel lattices are angelagert by diffusion. The particles pass the second induction stage obstacle-free. It serves with fast,� large changes of concentration for compensation purposes. In the third filter stage the remainder particles are then separated. In all three stages the loaded particles produce ensprechende in each case rivers, which are measured by highly sensitive amplifier stages and converted into digital signals. A data analysis software computes from it the appropriate number of particles and size distribution, which can be conveyed either over Bluetooth or USB to a computer. The data can be stored also directly on a SD/MMC memory card. The small dimensions, the very simple operation and the robust design make a very flexible employment possible for most diverse applications as e.g. in the environmental and aerosol research.
