Product Description
44L 750 PSI 4-Gas Calibration Gas – 15.0% Oxygen Deficiency Custom Blend
This custom 4-gas calibration cylinder is configured for programs requiring controlled simulation of significant oxygen depletion in a field-manageable format.
At 15.0% oxygen, this mixture validates alarm activation well below OSHA’s 19.5% requirement, ensuring detectors respond under substantial displacement conditions.
Gas Blend Composition
Hydrogen Sulfide (H₂S) – 25 PPM
Carbon Monoxide (CO) – 100 PPM
Methane (CH₄) – 2.5% (50% LEL)
Oxygen (O₂) – 15.0%
Balance – Nitrogen
This concentration is selected for high-risk confined space validation, emergency response simulations, and advanced detector performance verification.
Cylinder Specifications
Cylinder Size: 44L (1.5 Cubic Feet)
Fill Pressure: 750 PSI
Valve Type: C-10
Cylinder Material: Aluminum
Gas Reactivity: Reactive
Blend Type: Custom Mix
The 750 PSI configuration offers a balance between portability and usable calibration volume, making it suitable for recurring field deployment.
Operational Applications
• Severe oxygen-deficiency alarm validation
• Confined space entry simulation
• Industrial safety training environments
• Multi-gas detector performance testing
• Combustible and toxic gas sensor calibration
Methane at 2.5% equals 50% LEL for combustible sensor verification.
Carbon monoxide at 100 PPM supports standard toxic alarm setpoints.
Custom Production Notice
This 15.0% oxygen blend is produced as a custom calibration mixture. Lead times may vary based on production scheduling and cylinder preparation.
