Cybrand AEC Ltd delivers innovative services and products for ambient and exhaust emissions measurement (up to 5 gases & PM). We also provide support to a number of industrial partners and local authorities with field trials, data analysis, project management, product development, and much more.

 

Our vision is to improve environmental and occupational air quality, as well as process efficiency by helping companies meet technology requirements and overcome R&D challenges. Our experienced team has a proven track record of adapting to various applications.

​

• 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
