Technological and innovative market leader in fine particle measurement and sampling instrumentation.
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, our R&D department has continually increased the range of products which now consists of nearly 15 products for various different particle measurement needs. In addition to the instruments themselves, our aim is to provide our customers complete fine particle measurement solutions for different measurement applications.
Dekati instruments are used for example in the following areas:
Dekati company headquarters is located in Tampere, Finland where our organization is divided into R&D, Production, Quality control and Sales & Marketing. Along with high quality instruments Dekati provides various different services including after-sales support, installation services, consultation and user workshops. Dekati global product sales is organized via distribution network that enables us to provide local service to our 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.

Dekati - ThermodenuderDekati Thermodenuder makes detailed studies of soot particles possible by removing volatiles from automotive exhaust. Removal of the volatiles eliminates unwanted sample transformations. The high flow rate of the instrument makes it an ideal tool for use with ELPI™ (Electrical Low Pressure Impactor) and DMM (Dekati Mass Monitor), also manufactured by Dekati Ltd. |

Dekati - Service ProgramDekati service program is the basis of high quality and low down-time of Dekati instruments. The service program is divided into three levels of operation, daily, monthly and bi-annual. The daily and monthly service needs are carried out by the user, while the bi-annual service is carried out at the Dekati Ltd. calibration and testing facility. |

Dekati - Instrument SoftwareDekati real-time measurement instruments are operated with a Labview™ based software. The software is used to control the instrument as well as save the measured data. The software has been designed to make the instrument operation as simple as possible, and it is always included in the instrument shipment. Data processing spread sheets are also available for easy calculation and presentation of the measured data. |
