Menu Natural gas composition varies from source to source and often varies on a daily and seasonal basis. Using a calibration gas that is specifically designed for your application ensures that you will continue to achieve the best possible gas quality measurements.
Hydrocarbon gas mixtures for custody transfer, CO2 emissions monitoring
All EffecTech calibration gas mixture types that are included in both our ISO 17034 and ISO 17025 scopes of accreditation are issued with two certificates.
AccreditationsReturn to the Biomethane Calibration Gases page
EffecTech’s laboratory is accredited by the United Kingdom Accreditation Service (UKAS) for both composition and physical properties of natural gas. EffecTech holds UKAS ISO 17025 accreditation both as a calibration and testing laboratory.
As a calibration laboratory we have to demonstrate the highest levels of accuracy and traceability in our measurements and be able to defend the levels of uncertainty claimed on our certificates. This depth of understanding is not required by a routine testing laboratory.
