What Dekati Ltd does

Dekati Ltd. is a privately held Finnish designer and manufacturer of fine particle measurement and aerosol sample conditioning instrumentation, founded in 1993 and headquartered in Kangasala, Finland. The company operates two commercial lines: a high-end stand-alone Dekati® instrument portfolio (HR-ELPI®+, HT-ELPI®+, MPEC+™, eFilter™, DLPI+, HT-DLPI+, PM10 Impactor, DGI, eDiluter™ product range, DEED, Axial Diluter, Cyclone, DOFR™, Scale PARS-1m) and a Dekati Technologies sub-brand focused on customized particle sensors for OEM integration, notably the patented ePNC™ particle counter for PTI/RDE applications. Its products cover the 6 nm to 10 µm particle size range using a single measurement principle (electrical detection in the ELPI family and gravimetric analysis in the cascade impactor family), enabling complete conditioning-to-detection setups under one ISO 9001-certified, Finland-based manufacturing operation with up to five-year warranty.

Dekati monetizes through four revenue streams: (1) hardware sales of fine particle measurement instruments, (2) hardware sales of aerosol dilution and conditioning equipment, (3) professional services including maintenance, calibration and training, and (4) rental and leasing of measurement instruments. Pricing is quote-based and not publicly disclosed; products ship with standard two-year warranty extendable to five years. Distribution is hybrid: direct sales from the Finnish headquarters for Scandinavia and the Baltics, complemented by an authorized distributor network covering nearly 40 countries across Europe, North America, South America, East Asia, South Asia, Southeast Asia, and Oceania.

The customer base spans occupational health and industrial hygiene, engine and vehicle emissions, particle filtration research, air quality monitoring, stationary source emissions, non-exhaust vehicle emissions, aerosol dispersion studies, aerosol research and secondary aerosols, and carbon capture and storage. The company sells to thousands of customers worldwide, with no named flagship customers in the source material. Marketing is conducted through the corporate website, LinkedIn, YouTube tutorials, industry conference participation (IAC, EuroBrake, China Brake, ETH NPC, PM, UFP Symposium, Tyre Emissions & Sustainability), and a recurring webinar program. The firm is led by CEO Mikko Moisio with a senior team that includes a Vice-President/Director New Business Development, Director of Sales and Services, R&D Director, Production Manager, Business Development Manager/CMO, Head of Technical Support & Nordic Sales, Technology Manager, and Senior Scientist, all based in Finland.
