High Pressure Cylinders

CAC GAS supplies calibration gas mixtures which are prepared and analysed strictly following the most up-to-date guidelines, specifically the EPA Traceability Protocol Assay and Certification of Gaseous Calibration Standards. In addition to these protocol gases, CAC GAS offers ISO 17025 and ISO 17034 Continuous Emissions Monitoring gas standards, covering gases such as CO2, CO, O2, NO, NO2, and SO2.

All supplied gas mixtures are traceable to recognised authorities including NIST, NPL, NMI, or other national measurement institutes. Certification is provided by UKAS, NATA, DAkkS, or other ILAC MRA signatories, ensuring compliance with both local and international regulatory requirements.

Beyond calibration standards, CAC GAS also offers specialty gas mixtures designed for a range of environmental and industrial applications. These include mixtures for combustion efficiency analysis, biogas monitoring, landfill and soil remediation, as well as agricultural environmental monitoring. Gas standards TO 14, TO 15, and TO 17 are available, supporting measurement of volatile organic compounds (VOCs) in ambient air and soil contamination studies.
