We work with businesses and organisations both large and small for whom accurate particle measurement, micro-contamination control, filtration and environmental monitoring is essential to their core business goals.

ISO 9001:2008 Certification

We are currently certificated to the requirements of ISO 9001:2008 by Intertek Group PLC, who are accredited by the United Kingdom Accreditation Service (UKAS). UKAS, as an accreditation body, work with other similar bodies around the world to ensure that the standard of auditing is uniform and adequate. Some certification bodies do not have this accreditation and therefore the standard of their auditing has not been independently verified.
