ISO 17025:2017 Calibration

Etalonnage COFRAC d'analyzer et capteur

ETALONAIR is a fixed calibration laboratory accredited by the COFRAC's body to generate reference molar concentrations.
This means that a quality management system is in place and that our technical skills are recognised by the COFRAC's body.
Since its creation, the laboratory has remained entirely separated from testing laboratories and manufacturers, giving it a privileged position to guarantee the impartiality and confidentiality of your results.
The molar concentrations generated, without limitation, allow us to achieve the following benefits : lack-to-fit, repeatability, response time, interference sensitivity, oxygen influence, response factors, furnace efficiency (oxidation, gas conversion) for compounds listed in our accreditation field, or outside for all others.
The compounds in our scope are: CO, CO₂,O₂, SO₂, NO, NO₂,N₂O, CH₄, C₃H₈,C₂H₆, TOC and O₃.
We are willing to include other compounds on request, under and out of accreditation.

In 2014, most of the services provided to companies positioned in the field of gas analysis were considered overall insufficient, expensive, redundant and inefficient over time.
The result is a lack of availability and risks of malfunctions during use.
Based on this observation, ETALONAIR was founded to create a centre of competence capable of providing know-how on the performance of gas analysers and calibration under accreditation.
This core business has been supplemented over the years by renting and NOW SELLING.
