Driesen+Kern Measuring Instruments - DustTrak series dust monitors for the best choice of real-time aerosol measurement

Founded in 1977 as a sales company for measuring instruments, Driesen + Kern set out to develop, produce and sell its own measuring instruments in order to best meet the needs of its customers. Over the years, the company has become an important partner for companies in almost every industry because of Driesen + Kern's many years of experience and extensive expertise. Measuring instruments start at the design or planning stage, where the customer's measurement tasks and their requirements are important to sales representatives and developers. driesen+Kern offers solutions tailored to the customer's needs, from planning to creating board layouts to complete production, where the products are calibrated in the driesen+Kern laboratory with the appropriate test equipment for the respective physical measurement variables are calibrated in the Driesen+Kern laboratory with appropriate test equipment.

Dust monitors
The DustTrak range of dust monitors is the best choice for real-time aerosol measurement. In contrast to conventional weight-based sampling, the real-time dust monitoring offered by the DustTrak provides instant display and evaluation of measurement data, so these devices are used by customers for qualitative and quantitative determination of particles, while finding anomalous or conspicuous values that require a response within a few hours or at most a few days. Amongst other things, these devices are used for the classification of cleanrooms according to DIN ISO 14644 and EU GMP and are accompanied by a calibration certificate in accordance with ISO 21501-4. They are divided into two main sub-areas, single particle count and particle count. the DustTrak range of dust monitors can detect PM1, PM2.5, permeable size, PM10 and total size simultaneously without the need for a size selective inlet regulator.
