Calibrations of secondary standard ozone analysers
For those Member State NMIs that do not hold primary standards for ozone in air, the BIPM offers calibrations of secondary standard ozone analysers.
Interested laboratories are invited to contact Dr J. Viallon for the relevant calibration request forms.

|Matrix or material||Analyte or component||Dissemination range of measurement capability|
|Amount-of-substance fraction x(O3) / (nmol/mol)||Absolute expanded uncertainty
|synthetic air||ozone||0 to 1000|
- The notation Q[a, b] stands for the root-sum-square of the terms between brackets
- The claimed uncertainty includes a term coming from the best device under test
- Absolute expanded uncertainty: k = 2, level of confidence 95%
