A Comparative Study as a Quality Assurance of Stationary and Portable Hand-Held Ultrafine Particle Monitors
Authors: , , , ,
Abstract: In this study we investigated the performance of two portable hand-held measurement devices (Testo DiSCMini, Grimm NanoCheck) under real environmental conditions at an area on the new campus of the University of Applied Sciences Duesseldorf, which was influenced by construction activities and traffic. The values were compared to the data from a freshly calibrated SMPS (Grimm SMPS+C) as a reference system. The SMPS measured the particle number concentration as well as the particle number size distribution in a range from 5 nm to 350 nm. This was done as a quality assurance for the use of these portable devices for other measurement campaigns for detecting the particle number concentration in mobile applications by e.g. unmanned aerial systems, bicycles, or small aircraft. The results show a good correlation between all the systems. The agreement between the reference system and the NanoCheck was really good, but lower between the DiSCMini and the reference system. Due to the good correlation the data could be post processed with a correction function to reduce the deviation. Finally, it can be stated, that both systems work well under environmental conditions and are well suited for the mobile use for the investigation of ultrafine particle concentration.
