Pegasor develops and manufactures nanoparticle measurement devices based on electrical measurement and non-collective technology. Pegasor’s unique and patented measurement technology is among the best in its field. The device measures the nanoparticle emissions from various emission sources accurately and quickly even in challenging field conditions. Remaining in the forefront of measurement technology requires a profound knowledge of several specialist fields, and experienced and innovative experts are at the core of Pegasor.

Solid and multidisciplinary technical foundation

Pegasor’s development work of measurement devices combines diverse kinds of technical understanding. The competence edge is created primarily through the ability to apply information in product development. Pegasor’s core competence areas are:

  •   aerosol physics
  •   fluid mechanics
  •   thermal engineering
  •   material technology
  •   measurement electronics
  •   measurement algorithms 

‘Pegasor’s development aims not only for accuracy and reliability, but also for a simple and durable structure. A profound understanding of the various fields of measurement technology has enabled the streamlined design of nanoparticle measurement devices,’ says Senior R&D engineer Erkka Saukko.

Patented measurement technology for demanding conditions

Nanoparticle measurement is about extremely small signals. The accuracy requirement and minimization of various disturbances place high demands for the mechanical, material and device planning.

‘Pegasor’s measuring device is compact and structurally simple. There are as few parts and units as possible, and the most significant components carry out multiple functions. The overall system is greater than the sum of its parts. Simplicity proves itself when measurements are made in demanding conditions,’ emphasizes Pegasor’s CTO Kauko Janka.

Details related to the manufacturability of the measurement devices have also been taken into account in the design.

In challenging measurement conditions, such as industrial processes or the monitoring of the quality of outdoor air, the durability, stability and security of supply are emphasized.

Pegasor’s innovative solutions have an extensive patent portfolio. Various implementation methods and applications developed by Pegasor have also been patented.

Onwards through international research cooperation and joint development

Remaining in the forefront of development requires constant work with research and development. The roots of Pegasor’s innovation lie in the long-term research on electronic measurement methods of the Aerosol Physics Laboratory of Tampere University, which Pegasor’s experts have promoted through their doctoral theses. Pegasor participates actively in multidisciplinary research projects with universities and research institutions.

The development of Pegasor’s measuring devices is a continuous process. Development requests and feedback from customers are welcomed. The latest product development project on the expansion of the operational area of a measuring device was launched due to feedback from a customer. 

Vision

Pegasor aims to be a forerunner in the development of nanoparticle measurement. Pegasor’s measurement solutions work better, last longer and measure more accurately than previous solutions. They enable the accurate monitoring of indoor and outdoor air quality, as well as the development of ever cleaner technologies in the automotive industry, for example. Pegasor participates in solving the global air quality challenge and creating a cleaner and healthier environment.

 

user-friendly, scalable and cost-efficient technology

 

Increased research in nanoparticles raises public awareness of their adverse health effects. Up until now, nanoparticles have almost solely been measured in laboratory environments. Pegasor’s patented technology based on electronic measurement and simple structures allows for measuring nanoparticles wherever such applications are required: industrial sites, workplaces, traffic and various public and private spaces. Pegasor measures nanoparticles quickly and accurately in real time. 

Pegasor’s user-friendly, scalable and cost-efficient technology requires low maintenance, provides a reliable solution for the definition of nanoparticle concentration and integrates easily into larger measurement systems. Pegasor’s expertise in the development of measurement equipment used in aerosol physics is world-class. Close collaboration with universities and other research institutes has shown Pegasor’s technology to be reliable.  

Traffic

The nanoparticle emissions of traffic have a major impact on the quality of air and people’s health. Nanoparticles travel deep in the lungs, causing damage in the pulmonary alveoli and the circulatory system. According to recent estimates, fine particles cause approximately 7 million premature deaths worldwide every year. 

Traffic and combustion engines are major sources of nanoparticle emissions. Nanoparticle measurements in the automotive industry and traffic help identify the most significant sources of emissions and reduce the level of emissions. Pegasor serves car and engine manufactures and vehicle inspection stations.

Car and engine manufacturers: The measurement of nanoparticle emissions is important in the product development and quality management of new cars and engines. Some new cars may have faulty filters that allow nanoparticles to travel through them. Quality management and measurement equipment ensure that no cars equipped with faulty filters are released to the market.  

Vehicle inspection stations: The regulation of nanoparticle emissions will be even more restrictive in Europe in the coming years. Decision-makers are under pressure to place stricter limit values for the nanoparticle emissions of traffic. This regulation requires frequent inspection and monitoring of vehicles. Pegasor’s measurement technology is ideal for vehicle inspection stations due to its reliable, cost-efficient and user-friendly measurement solutions.  

Quality of air in cities

Large cities need to control the level of harmful emissions. Clean air is a competitive advantage, and its significance is growing continuously. The need to measure, develop and improve the quality of air in large cities is increasingly important. Current measurements focus on fine particles but often omit nanoparticles.

As more research data becomes available, the need to measure the number of nanoparticles in the air is highlighted more and more. Pegasor’s measurement technology allows for real-time air quality monitoring even in demanding authentic settings. The measurements help in determining the sources of nanoparticle emissions and, consequently, initiating the measures to reduce the level of emissions. The device transmits real-time measurement data of variations in the quality of air. This data can be used widely in the development efforts of cities. 

Indoor air quality

Traffic generates emissions that are harmful to health, and they may enter the indoor air of buildings if they are not filtered. Poor quality of air in cities also makes the quality of indoor air worse. Pegasor’s measurement devices provide a solution for measuring the quality of air in public and private buildings.

Strategic partnerships with industrial partners (OEM)

Pegasor provides a strategic partnership for industrial manufacturers who require nanoparticle measurement technology solutions in addition to their own technology. Pegasor’s measurement device is a stand-alone instrument, but it is effortless to integrate it into a larger system. Pegasor can either supply a ready-made technology solution or license its technology out to its partners.
