About Us

For almost 15 years, Apex Emission Testing has been delivering quality, reliable, and value adding, environmental assessment services to Southern Africa.

Founded in 2004, Apex Emission Testing prides itself in being able to say that it is one of the longest running air quality and air emissions test laboratories in South Africa.

In January 2017, Apex Emission Testing obtained SANAS Accreditation to ISO 17025 for "Testing and Calibration Laboratories", and not simply to ISO 17020 for "Inspection Bodies", briefly and voluntarily withdrawing this accreditation, to further refine and improve our Quality Management System so as to better incorporate international best practices and experience obtained in the USA and Australia.


Apex Emission Testing is proud to announce that we are once again approaching the time for us to submit our SANAS accreditation application.

Our Services
