IN CRITICAL
ENVIRONMENT TESTING
HeX TESTING operates in critical environments where contamination management is a natural requirement (clean rooms and controlled environments) as well as in environments with non-specific pollution (offices, buildings open to the public, housing, etc).
HeX TESTING performs on-site testing, the results are then analyzed to provide a complete and comprehensive solution to the client. This mission requires a perfect knowledge of the field of application and our expertise meets these needs.
HeX TESTING considers for more than 15 years that environmental controls must be part of a global approach to risk management.
For over 15 years HEX has been of the opinion that environmental control
should be part of a comprehensive approach to risk management.
