Product Description
34L Disposable 4-Gas Calibration Cylinder – 17.0% Oxygen Deficiency
This compact disposable 4-gas calibration blend is engineered for technicians who require deeper oxygen alarm validation in a portable, simplified format.
Gas Blend Composition
Hydrogen Sulfide (H₂S) – 25 PPM
Carbon Monoxide (CO) – 100 PPM
Methane (CH₄) – 2.5% (50% LEL)
Oxygen (O₂) – 17.0%
Balance Gas – Nitrogen
At 17.0% oxygen, this mixture creates a high-deficiency environment to confirm detector activation under stronger displacement conditions.
Cylinder Specifications
Cylinder Volume: 34L (1.2 Cubic Feet)
Fill Pressure: 500 PSI
Valve Type: C-10
Cylinder Material: Aluminum
Cylinder Type: Disposable
Gas Reactivity: Reactive
The 500 PSI disposable format reduces handling complexity while delivering reliable alarm simulation for field use.
Recommended Applications
• Portable multi-gas detector bump testing
• Confined space entry kits
• Oxygen alarm verification
• Maintenance technician calibration
• Combustible and toxic sensor validation
Methane at 2.5% equals 50% LEL for combustible sensor testing.
CO at 100 PPM aligns with common low-alarm setpoints.
Oxygen Tier Context
20.9% → Ambient reference
19.0% → Mild deficiency
18.5% → OSHA threshold simulation
18.0% → Enhanced deficiency
17.0% → High-deficiency alarm validation
This 34L 17.0% configuration is selected when programs require stronger alarm confirmation in a lightweight, disposable format.
