OEM Sensor System

Aerosol sensors for production and process monitoring


The sensors manufactured by Palas® work according to the proven principle of single particle measurement via the scattered light method with high resolution to determine the distribution of particle size and concentration.

They are individually configurable, e.g. via the following parameters / interfaces (from 100 units / configuration):

  • Volume flow (1 l/min – 16.7 l/min)
  • Measuring range (0.145 µm – 40 µm)
  • Number concentration range (0 P/cm³ – max. 10,000 P/cm³ resp. 0 P/cm³ – max. 500,000 P/cm³)
  • Interfaces USB (others on request)
  • Analog and digital outputs
Different variants and characteristics are available, which can be individually adapted to the needs of the user. This means that many applications can be covered, e.g. even under non-atmospheric conditions.

Our specialists for OEM sensors and integration are available to you as experienced contacts for the precise definition of your requirements - of course not only at our headquarters in Karlsruhe, but also at your site.


  • Individual configuration according to customer requirements
  • Already realisable from quantities of 100 units / configuration
  • Direct evaluation of data and provision for further processing
  • Mechanically robust, durable and free of maintainance
  • Unambiguous and specific calibration of particle size determination via NIST-retraceable monodisperse aerosol
