partector 2

The world's smallest multimetric nanoparticle detector


The naneos partector 2 is the world's smallest multimetric nanoparticle detector. The partector 2 uses dual non-contact detection stages to measure not only lung-deposited surface area like the standard partector, but also particle number concentration and average particle diameter. Additionally, ultrafine particle (UFP) surface and ultrafine particle mass concentrations are calculated and displayed. In contrast to some of our competitors, the UFP mass is displayed online, and it is calculated using the measured diameter of the particles, rather than estimated by a simple multiplier for LDSA.

The 7 key benefits of the partector 2 compared to traditional nanoparticle detectors, such as handheld CPCs, are:

 multiple meaningful metrics
 miniature and lightweight
 hassle-free measurement
 fast startup time
 orientation-independent operation
 wide particle concentration range
 great battery life


  • Simultaneous measurement and online display of 5 metrics: LDSA, particle number, average particle size, surface area, UFP mass (PM0.3)
  • High time resolution: 1 second
  • LDSA concentration range: from 0 - 12'000 µm²/cm³
  • Number concentration range: from 0 - 106 cm-3
  • Average particle diameter range: from 10 - 300 nm
  • Surface area concentration range: 0 - 50'000 µm²/cm³
  • UFP mass range (PM0.3): 0 - 2'500 µg/m³
  • Typical accuracy: 30%
  • Size: 142x88x34mm
  • Weight: 415 grams
  • Internal rechargeable Li:Ion battery, run time typically 24 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
  • Two years warranty

  • Data access from anywhere over an internet link.
  • Download of measurement data possible.



Alarm box

Visual and audible alarm

  • Robust audible and visible alarm for noisy environments or laboratories.
  • Alarm threshold can be set via partector 2 or can be a hardcoded value inside the alarm hardware.
  • Alarm acknowledgement via partector 2.
  • Partector 2 sends its data over wireless communication to the alarm box.
  • The alarm box can also forward the data over GSM to the IoT server.
  • Can send text or email messages to a person responsible for lab safety.

OEM version

For long-term measurements

  • No internal pump, flow must be provided externally
  • Allows connection of larger pumps with long lifetimes for continuous monitoring

Silent pump option

For measurements in places where pump noise is disturbing

  • The standard pump of the partector 2 can be replaced with an ultra silent one.
  • Pump operates at ~21 kHz, beyond what most people can hear and thus makes no audible noise emissions even in very quiet environments.
  • Children might hear the pump, but in our testing at most up to 1m distance.
  • Measure in noise-critical environments such as bedrooms, hospitals, schools etc.
