PEMS Overview:
PEMS testing refers to the use of Portable Emissions Measurement Systems to assess vehicle emissions under real-world driving conditions. Unlike laboratory-based tests, PEMS devices are mounted directly onto vehicles and capture emissions data during actual road use—providing a more accurate reflection of environmental impact.
Key Features
• On-Road Testing: Measures exhaust gases during typical driving scenarios such as acceleration, idling, and braking.
• Real-Time Monitoring: Captures pollutants including CO₂, NOₓ, carbon monoxide, and particulate matter.
• Regulatory Compliance: Widely adopted by regulatory bodies (e.g. EU, US EPA) to verify emissions standards beyond controlled lab environments.
Benefits
• Enhanced Accuracy: Identifies emissions spikes that may be missed in laboratory settings.
• Cost Efficiency: Reduces reliance on expensive dynamometer setups.
• Policy Alignment: Became mandatory in the EU for light-duty vehicle type approval in 2016, following concerns over discrepancies between lab and road emissions (e.g. Dieselgate).
Technical Capabilities
• Measures gases such as:
• Nitric oxide (NO) and nitrogen dioxide (NO₂), combined as NOₓ
• Carbon monoxide (CO) and carbon dioxide (CO₂)
• Oxygen (O₂) levels
• Optional modules can track:
• Particulate number (PN)
• Ambient conditions (temperature, humidity)
• GPS and driving patterns

PEMS testing
Portable emissions measurement systems (PEMS) consist of a testing device that is small and light enough to be mounted inside or outside a vehicle or machine that is in normal operation during testing. This is the most accurate method of testing real-world duty cycles, which are difficult to replicate on a traditional dynamometer.

Ambient Air Quality Testing
Air quality monitoring is the process of measuring and assessing the pollutants present in ambient air. The data gathered can then be analysed by collating the pollutant types, their quantity and measuring against specific air quality standards.

Live Emissions Analysis & Reporting
Monitor live data through any internet connected device with our comprehensive and customisable user dashboard. If an internet connection is not possible, data can be stored locally on the measuring device and analysed at a later date.
