What Pegasor Oy does

Pegasor Oy is a Finnish privately held technology company founded in 2008 and headquartered in Tampere, Finland, specializing in real-time measurement of ultrafine particles (UFP) and nanoparticles. The company has been an integral part of France-based Capelec Group since 2021, which specializes in periodic technical inspection (PTI) equipment and provides primary commercial channels for Pegasor's products. Pegasor's entire product portfolio is built around a patented electrical aerosol detection technology that combines diffusion charging with an 'escaping current' method, enabling particles to flow through the sensor without being collected — yielding multi-year maintenance intervals, no moving parts, no working fluids, and direct hot-exhaust measurement up to 200°C. The portfolio consists of the PPS-G2 OEM sensor (the technology core), the PPC standalone particle counter for vehicle inspection, the Airam outdoor air quality monitor, the PPS-1000 indoor air quality monitor launched in June 2026, and the Pegasor Cloud Portal for remote data and device management.

Pegasor sells to five primary customer segments: vehicle inspection stations and PTI regulators (where PPS-G2 is certified by PTB, NMI, and METAS in Germany, Netherlands, Belgium, and Switzerland); engine and vehicle manufacturers for R&D and certification testing; urban air quality monitoring networks (aligned with EU Directive 2024/2881); airport operators and aviation emission programs (UNIC project); and indoor air quality / occupational hygiene buyers. Revenue mechanics span OEM sensor licensing, capital equipment sales of standalone instruments, an optional cloud subscription, and calibration services, distributed through direct enterprise sales, a global distributor network, the Capelec channel, and OEM integration partnerships. The company participates in numerous EU and Finnish research programs (METECH, UNIC, HAQT, HERE, CLEEN, GIANT) that provide both technology validation and pipeline visibility into next-generation emission regulations.

Revenue model

1. Particle Sensor Hardware Sales (OEM): Pegasor sells its PPS-G2 particle sensor to OEM integrators and manufacturers who embed the technology into their own systems such as vehicle inspection equipment, PEMS devices, and air quality monitoring platforms. Sensors are available as off-the-shelf technology solutions or through licensing agreements.
2. Standalone Particle Instruments: Pegasor manufactures and sells complete standalone instruments (PPC, Airam, PPS-1000) for emission testing, air quality monitoring, and indoor UFP measurement. These are sold directly and through distributors to vehicle inspection stations, research institutions, airports, and industrial facilities.
3. Cloud Portal Subscription (Optional): The Pegasor Cloud Portal provides optional remote data monitoring, storage, reporting, and firmware management services for Airam and PPS-1000 users, likely as a subscription add-on to hardware purchases.
4. Calibration and Support Services: Pegasor offers calibration services and expert technical support to ensure consistent and reliable instrument performance, particularly for high-throughput vehicle inspection environments.

Core offering

Pegasor Oy designs, manufactures and sells ultrafine and nanoparticle measurement devices based on a patented electrical aerosol detection technology (combining diffusion charging with an 'escaping current' technique). Its portfolio includes the PPS-G2 OEM particle sensor and complete standalone instruments (PPC, Airam, PPS-1000) used for vehicle emission inspection, engine R&D, urban air quality monitoring, and indoor ultrafine particle (UFP) measurement. Optional cloud-based data management and remote monitoring is delivered through the Pegasor Cloud Portal.

Product overview

Pegasor Oy is a Finnish technology company specializing in ultrafine particle and nanoparticle measurement. Its product portfolio consists of two interconnected lines: particle sensors (PPS-G2) and particle instruments (PPC, Airam, PPS-1000). All instruments are powered by the PPS-G2 sensor, which uses patented electrical aerosol particle detection technology combining diffusion charging with an escaping current. The PPS-G2 sensor is available both as a standalone OEM component and as the sensing core inside complete instruments. The PPC is a complete standalone particle counter for exhaust/emission testing, approved for nPTI in multiple European countries. The Airam is a standalone outdoor air quality monitor aligned with the new EU Ambient Air Quality Directive 2024/2881. The PPS-1000 is a compact indoor air quality monitor with integrated cloud connectivity. All instruments can connect to the Pegasor Cloud Portal for remote data access and management. Since 2021, Pegasor has been part of the Capelec Group.
