Whether for research & development, regulatory preparation or benchmarking, our customers turn to us for unrivalled expertise in the application of Portable Emissions Measuring Systems (PEMS). We are now pleased to offer N2O, NH3 and VOC tailpipe analysis in addition to gaseous and particulate matter emissions (patent pending - PCT International Patent Application PCT/GB2022/050973). We are able to test globally, wherever and whenever you need us, including your laboratory.

Test methods
- Regulatory – pre-type-approval design and validation and post-type-approval in-use surveillance and testing for Real Driving Emissions (RDE) and Worldwide Harmonised Light Vehicle Test Procedure (WLTP)
- Non-regulatory – off-cycle real-world testing
- CWA 17379 from CEN for tailpipe NOx
- Stage V In-Service Monitoring (ISM)
- Euro VI In-Service Conformity (ISC)
- USEPA CFR 1065
- Benchmarking – vehicles and products
- Intervention – before and after testing for products
- Problem diagnosis and resolution.
We can test to these additional standards.
