Since a few months you may encounter 2 Google Street View cars in the Amsterdam area to map the air quality at street level. Utrecht University (IRAS) is responsible for the technical and scientific support of the project and j.j. bos has supplied a number of (TSI) systems in the cars to measure the air quality.
Our company j.j. bos b.v. is partner of TSI in the Benelux since 1972. Therefore it is our pleasure to introduce you to the latest tool TSI offers on the market of combustion emission research, the NPET or Nanoparticle emission tester. This Nanoparticle emission tester is dedicated to diesel emission machinery testing and it is designed as a portable tool for use in the field or the lab.
Optical Particle Sizer model 3330 (OPS) is a light, portable unit that provides fast and accurate measurement of particle concentration and particle size distribution using single particle counting technology. Backed by over 40 years of aerosol instrumentation design experience, the OPS uses state-of-the-art optics with 120° light collection and sophisticated electronics processing resulting in precision, high quality data. Rigorous factory calibration standards ensure measurement accuracy. The model 3330 particle sizers can be used alone, or it can be placed in TSI's weatherproof Environmental Enclosure.
