Product Description
High-Capacity CO / Pentane / Oxygen Calibration Gas for Extended Field Use
This calibration gas mixture contains Carbon Monoxide (CO) 35 PPM, Pentane (C₅H₁₂) 0.14% (10% LEL), and Oxygen (O₂) 18.0%, balanced in nitrogen. Supplied in a 221L steel disposable cylinder at 250 PSI with a CGA-165 valve, this blend is designed for extended calibration operations and high-usage environments.
The increased cylinder volume allows for longer usage intervals between replacements, making it ideal for teams performing frequent calibrations, large-scale monitoring programs, or multi-device servicing.
