Product Description
60L 1000 PSI 4-Gas Calibration Gas – 17.0% Oxygen Deficiency Blend
This 4-gas calibration cylinder is engineered for safety programs requiring deeper oxygen-displacement validation beyond standard alarm threshold checks.
Gas Blend Details
Hydrogen Sulfide (H₂S) – 25 PPM
Carbon Monoxide (CO) – 100 PPM
Methane (CH₄) – 2.5% (50% LEL)
Oxygen (O₂) – 17.0%
Balance – Nitrogen
The 17.0% oxygen concentration creates a pronounced deficiency environment to confirm detector performance under stronger oxygen displacement conditions.
Cylinder Specifications
Cylinder Size: 60L (2.1 Cubic Feet)
Fill Pressure: 1000 PSI
Valve Type: C-10
Cylinder Material: Aluminum
Gas Classification: Reactive
The 1000 PSI fill provides extended calibration capacity while maintaining compatibility with widely used C-10 fixed-flow regulators.
Recommended Applications
• Confined space compliance validation
• Oxygen alarm stress testing
• Scheduled bump test programs
• Industrial hygiene verification
• Combustible and toxic sensor calibration
Methane at 2.5% equals 50% LEL for combustible sensor validation.
CO at 100 PPM aligns with typical low-alarm calibration requirements.
Oxygen Concentration Framework
20.9% → Ambient air reference
19.0% → Mild deficiency simulation
18.5% → OSHA threshold validation
18.0% → Controlled enhanced deficiency
17.0% → High-deficiency alarm confirmation
The 60L 17.0% configuration is commonly selected for programs requiring stronger alarm verification without moving into extreme oxygen displacement scenarios.
