Giving meaning to measurement
Since 2015, our laboratory has been accredited to generate reference gas concentrations measured on continuous signal gas analysers.
Internal and standardized methods are used to obtain calibration results.
Our calibration benches, designed by ETALONAIR, allow us to achieve a wide range of reference concentrations, in single dilution (binary mixture) or in double dilution (ternary mixture).
We are accredited on the following compounds, either principal or interfering: O₂, CO, CO₂, NO, NO₂, SO₂, C₃H₈, and CH₄.
Many other compounds are available outside of accreditation: N₂O, NH₃, He, C₂H₆, etc.
The laboratory shall issue either a verification statement (conformity assessment against customer specified requirements) or a calibration certificate.

COMMITMENT - KNOWLEDGE
Our experience and our own research in metrology make it possible to perform the calibration of your analyzer with increased time savings and deliver the report as soon as the instrument returns.
Our processing capacity makes it possible to absorb a large number of requests throughout the year.
Our know-how in the development of reference concentrations, binary or ternary, allows us to respond to all requests.
Our planification skills allows to shortern delivery time even more.
Our mastering of calibration combined with automation make us extremely responsive and impartial on the results, with a quick delivery of the report.
Our quality manual, sent on request, presents all our policies, commitments and provisions to meet all the requirements of ISO 17025.
EFFECTIVENESS
The synergy between our teams ensure continuity of service and saves time to resolve non-conformities.
Outsourcing repair, maintenance and calibration under a same banner allows you to reduce costs, dowtime and transport damages.
