Pegasor Oy (Ltd) news

Pegasor has been in close collaboration with Groupe Renault since 2009. The collaboration has been particularly active in recent years. Renault uses Pegasor’s measurement technology in the development of new engine types. Pegasor’s PPS-M sensor monitors the nanoparticl

Efforts to reduce traffic emissions in Europe advance to the next level in 2021, when the number concentrations of vehicles’ particulate matter emissions and whether they exceed the limit value will begin to be monitored with periodic vehicle inspections. Due to the inaccuracy of the current particulate measurement solution, the system has been unable to detect even the most polluting vehicles. The detection of defective and obsolete exhaust purification devices is vitally importa

A study led by Vrije Universiteit Brussel tested various candidates to find feasible technologies for the next generation Periodic Technical Inspection for Particle Number limits (PN-PTI). New test methods for diesel vehicle soot emission inspection are badly needed, as modern engines produce soot in particle size that current opacimeter technology cannot detect, even from a vehicle with completely removed particulate filter. The highlights of the study are the extreme reliability of the Pega

A study led by Finnish Meterological Institute showed that Pegasor AQ Urban provides long term measurements with reliable and repeatable results, when compared with reference grade methods. In the study several different instrument types were tested to study their applicability to complement standard methods in air quality measurements.
