Dekati develops, manufactures and markets instrumentation needed in fine particle measurement and sampling. In 1995, Dekati introduced the world’s first real-time fine particle concentration and size distribution measurement instrument. Since then, we’ve continually expanded our product line which now consists of various products for different particle measurement needs. Along with high quality instruments Dekati also provides services including calibration and installation services, after-sales support, measurement consultation and user workshops.

Dekati® Measurement Solutions

Dekati’s high quality measurement solutions for aerosol measurements include both fine particle measurement and sample conditioning instruments. New products and product improvements are continually being developed in the Dekati R&D team that works in close co-operation with the world’s leading universities and companies. All our instruments are designed and manufactured in Finland according to strict quality requirements and provided with a standard two year warranty.

Dekati key areas of expertise within aerosol measurements include:

  • Fine particle size, concentration and distribution detection
  • Mass, number and surface area measurements
  • Charge detection
  • Dilution and sample conditioning

Dekati® Instruments are used in the following application areas:

  • Combustion process emissions and research
  • Engine development and emission measurements
  • Environmental ambient aerosol research and monitoring
  • Pharmaceutical drug screening and inhalator R&D
  • Nanotechnology and material processing
  • Particle research

Dekati® Instruments

  • All units original Dekati® design
  • 20 years of experience in aerosol instrumentation
  • All units manufactured and calibrated in Finland
