Dekati Ltd.

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. .

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

Each and every Dekati® Instrument is thoroughly tested with traceably calibrated flow, pressure, temperature, voltage, current and particle measurements. Additionally, all Dekati® Instruments go through rigorous type-approval tests, including instrument response tests for changes in temperature, pressure and humidity. The robustness of our instruments is guaranteed through misuse tests making sure that the instruments are ready for any environment. These procedures ensure that every instrument shipped operates according to their specifications and the measurement data is reliable and reproducible.

Dekati Contacts

Dekati sales and after sales support are globally organized through local representatives. Our suppliers are continuously given training and information on our product line to be able to provide you with current and accurate information on our products. Dekati has currently official representatives in nearly 40 countries, and our customer base includes thousands of customers worldwide

High quality and reliability are key features for all Dekati Ltd. products. While Dekati products are high-end scientific instruments, they are designed to be used in the field rather than in a laboratory. This sets high requirements for the quality as the used technology and the instruments have to be tested for field conditions. All Dekati instrument models go through a rigorous type-approval test, where the instrument response is tested with changes in temperature, pressure and humidity. In addition, vibration and misuse tests are carried out to make sure that the instruments are ready for any environment.

All of Dekati individual instruments are tested with traceably calibrated flow, pressure, temperature, voltage and current measurements. In addition a reference test is carried out for each measurement instrument against the original reference instrument calibrated with particles by an independent aerosol laboratory. The reference instrument response is verified annually with traceable gravimetric measurements. These procedures ensure that every shipped instrument operates according to the specifications and that the measurement data from the instrument is reproducible.

Dekati Quality manager oversees monitoring and development of quality at Dekati. This includes analyzing long-term testing data and the development of quality processes within the company.
