Product Description
High-Capacity Multi-Gas Calibration Gas (CO / CO₂ / CH₄ / O₂) Custom Mix – 221L Disposable Cylinder
This 221L custom calibration gas mixture is designed for high-volume calibration environments, delivering a balanced blend of Carbon Monoxide (CO), Carbon Dioxide (CO₂), Methane (CH₄), and Oxygen (O₂) for extended-use detector verification.
Built for operations that require longer calibration cycles and reduced cylinder replacement frequency, this larger disposable cylinder supports efficient workflow continuity across industrial safety programs and EHS compliance routines.
The inclusion of 50% LEL methane enables combustible gas response validation, while CO and CO₂ concentrations ensure accurate toxic and environmental monitoring checks. Oxygen at 20.9% provides atmospheric baseline calibration, allowing full multi-sensor verification in a single gas application.
Packaged in a disposable steel cylinder with CGA-165 connection at 250 psi, this non-reactive calibration gas offers a practical balance between capacity, portability, and ease of handling.
Ideal for teams performing frequent bump testing, multi-unit calibration, or facility-wide safety checks, this custom mix supports consistent performance with fewer interruptions.
