The world's smallest nanoparticle detector


The naneos partector is the world's smallest nanoparticle detector. We have designed it to be as simple to use as possible. It is based on a novel non-contact electrical detection principle which needs nearly no maintenance. It measures the lung-deposited nanoparticle surface area, which has been identified by toxicologists as the most important physical particle metric when it comes to health effects.

The 7 key benefits of the partector compared to traditional nanoparticle detectors, such as handheld CPCs, are:

 miniature and lightweight
 hassle-free measurement
 fast startup time
 works in any orientation
 wide particle concentration range
 meaningful metric
 great battery life


  • LDSA measurement with a time resolution of 1 second (internal instrument time constant 4s; faster on request)
  • Wide concentration range, from 1-20'000 µm²/cm³
  • Wide particle size range, from 10 nm to 10 µm
  • Size: 134x78x29mm - fits in a typical shirt pocket
  • Weight: 400 grams
  • Internal rechargeable Li:Ion battery, run time typically 18 hours in new devices
  • Data storage on a µSD-card (enough space for many years of data!)
  • Graphical display
  • High concentration alarm with adjustable threshold
  • Includes a java data analysis tool that runs on all major operating systems



The partector comes in a rugged transport case that contains all accessories necessary:

  • Protective sleeve - protects the partector from dirt, water and shocks, and contains a belt loop to attach it to a belt for personal monitoring.
  • Micro-SD-card to USB adapter - to easily read data from the partector's integrated micro-SD-card.
  • USB charger - a standalone USB charger to either charge the partector or run it 24/7 indefinitely
