Product Description
66L 1150 PSI 4-Gas Calibration Gas – 17.0% Oxygen Deficiency Simulation
This 4-gas calibration cylinder is engineered for programs requiring deeper oxygen-deficiency alarm validation beyond standard OSHA threshold testing.
Gas Composition
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 condition, ensuring alarm response is validated under stronger displacement scenarios.
Cylinder Specifications
Cylinder Volume: 66L (2.3 Cubic Feet)
Fill Pressure: 1150 PSI
Valve Connection: C-10
Cylinder Material: Aluminum
Gas Reactivity: Reactive
The 1150 PSI fill supports extended calibration cycles for organizations managing high-usage detector fleets.
Operational Use Cases
• Advanced confined space compliance programs
• Aggressive oxygen alarm validation
• Detector performance stress testing
• Industrial hygiene verification procedures
• Combustible and toxic sensor calibration
Methane at 2.5% equals 50% LEL for combustible sensor validation.
CO at 100 PPM aligns with common low-alarm setpoints.
Oxygen Tier Hierarchy
20.9% → Ambient baseline
19.0% → Mild deficiency
18.5% → OSHA threshold simulation
18.0% → Enhanced deficiency
17.0% → High-deficiency alarm validation
The 17.0% configuration is selected when programs require stronger confirmation of oxygen alarm activation performance.
