- Regulatory authorities and researchers
Key use cases include:
- Emission measurements in engine and chassis dynamometers
- Portable Emissions Measurement Systems (PEMS)
- Real Driving Emissions (RDE) testing
- Aircraft emission measurements
Pegasor’s sensors are designed for flexibility and high performance, even under rapidly changing conditions.
Pegasor Technology in Emission Testing
✅ Pegasor PPS-G2
A robust, real-time particle sensor designed for integration into engine test systems and mobile platforms.
- Particle number and size measurement
- Compact, rugged, and maintenance-free operation
- Ideal for NPTI, PEMS and RDE
- High tolerance to exhaust temperatures and vibration
✅ Pegasor PPC
A compact, portable particle counter for DPF testing, vehicle inspection, and spot checks

Trusted in Periodic Technical Inspections (PTI)
Pegasor’s PPS-G2 sensor is an approved method for PTI (Periodic Technical Inspection) particle number measurements in:
- 🇩🇪 Germany
- 🇧🇪 Belgium
- 🇳🇱 The Netherlands
- 🇨🇭 Switzerland
These countries have adopted particle number (PN) concentration limits as part of their PTI protocols, making reliable sensor performance critical. The PPS-G2 provides:
- Real-time, accurate particle number data
- Reliable operation in inspection environments
- Robust operation with minimal maintenance
- Easy integration into other systems
With vehicle emissions checks becoming more stringent, Pegasor provides inspection stations and authorities with the tools they need to stay compliant and effective.
PEMS and Real-World Testing
As emission regulations shift toward real-world driving conditions, the demand for PEMS-compatible sensors is growing fast. The PPS-G2 particle sensor is widely used in Portable Emissions Measurement Systems and RDE testing worldwide. While PPS-G2 is designed for integration, the PPC instrument can be used as a complete ready solution for testing emissions on-board under real-world conditions.
Its key advantages for mobile applications:
- Low power consuption
- No need for external pumps if PPC is used
- Insensitivity to vibrations
- Fast and stable real-time output
- Low-maintenance operation
Whether you’re building your own system or integrating into a commercial PEMS unit, Pegasor technology is built for the road.
Applications Across Mobility Applications
Pegasor’s instruments are used in a wide range of applications:
- Emission and type approval testing
- In-use compliance testing
- Research and development
- Aftertreatment operation testing
- Evaluation of alternative fuels and combustion systems
