Particle Emission Measurement Solutions for Diesel and Gasoline Engines
Engine emissions are under increasing regulatory scrutiny. Accurate particle measurement is no longer just for the lab but it is essential for compliance, R&D, and roadworthiness. Pegasor’s patented sensor technology provides real-time data on Particle Number (PN) and Particle Size, delivering laboratory-grade precision in rugged, industrial-grade hardware.
Whether you are optimizing non-road engines, on-road vehicles, marine vessels, or aviation turbines, Pegasor is built to deliver in the most demanding environments.

Core Technology: The PPS-G2 and PPC Platforms
✅ Pegasor PPS-G2: The OEM Integration Standard
The PPS-G2 is a robust, real-time particle sensor designed specifically for integration into engine test systems and mobile platforms.
- Fuel-Neutral: Optimized for Diesel, Gasoline Direct Injection (GDI), and Marine Residual/Distillate fuels.
- Industrial Ruggedness: Maintenance-free operation with no moving parts or working fluids—ideal for remote or offshore applications.
- High Tolerance: Operates reliably under extreme exhaust temperatures and high vibration.
- Smart Diagnostics: Extensive internal monitoring for reliable, repeatable data.
Pegasor Sensor PPS-G2 – PNC for NPTI integration
✅ Pegasor PPC: The Portable Particle Counter
The PPC is a compact, standalone instrument designed for immediate use in the field, workshop, or on-board vessels. Unlike the integrated sensor core, the PPC is a complete, ready-to-use solution.
- Portable & Rugged: Ideal for DPF/GPF testing, vehicle inspection, and spot checks.
- No External Pump Required: Features an internal flow control for simplified operation.
- Real-Time Diagnostics: Instant PN readings for fast, on-site emission verification.
- Low Maintenance: Designed for high-volume use with minimal service requirements.
The Global Standard for Periodic Technical Inspection (nPTI)
The Pegasor PPS-G2 is a field-proven, approved technology for nPTI Particle Number (PN) measurements in leading regulatory markets::
- 🇩🇪 Germany
- 🇧🇪 Belgium
- 🇳🇱 The Netherlands
- 🇨🇭 Switzerland
As national frameworks adopt stricter PN concentration limits, the PPS-G2 provides the regulation-aligned core needed for official compliance. It handles the high-throughput demands of inspection stations while maintaining the accuracy required by law.
Marine and Real-World Emissions
As maritime and RDE (Real Driving Emissions) regulations shift toward stricter particle monitoring, the PPS-G2 and PPC are engineered for the most difficult conditions:
- Corrosion & Vibration Resistance: Built to withstand the harsh environments of engine rooms and exhaust stacks.
- Fast Response: 0.2 s response time for capturing transient emission events.
- Low Power Consumption: Minimal draw on vehicle or vessel electrical systems.
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:
- In-Use Compliance: Long-term monitoring of fleet and vessel emissions.
- Aftertreatment R&D: Real-time efficiency testing of DPF, GPF, and Marine Scrubber systems.
- GDI & Diesel Focus: Evaluating modern combustion systems and emission reduction strategies.
