Product Description
Compact 34L 4-Gas Calibration Cylinder – 18.0% Oxygen Deficiency
This disposable 4-gas calibration cylinder is engineered for mobile technicians and smaller compliance programs requiring enhanced oxygen-deficiency simulation.
Gas Composition
-
Hydrogen Sulfide (H₂S): 25 PPM
-
Carbon Monoxide (CO): 100 PPM
-
Methane (CH₄): 2.5% (50% LEL)
-
Oxygen (O₂): 18.0%
-
Balance Gas: Nitrogen
The 18.0% oxygen concentration provides a controlled deficiency environment for validating alarm response below OSHA’s 19.5% oxygen standard.
Cylinder Configuration
Cylinder Volume: 34L (1.2 Cubic Feet)
Fill Pressure: 500 PSI
Valve: C-10
Material: Aluminum
Cylinder Type: Disposable
Gas Classification: Reactive
The 500 PSI disposable format offers lightweight handling and simplified field deployment without long-term cylinder management.
Ideal For
• Portable gas monitor bump testing
• Confined space entry kits
• Maintenance technicians
• Low-volume compliance programs
• Combustible and toxic gas sensor verification
Methane at 2.5% equals 50% LEL for combustible sensor validation.
CO at 100 PPM supports standard low-alarm calibration thresholds.
Oxygen Tier Comparison
20.9% → Ambient air simulation
19.0% → Early deficiency validation
18.5% → OSHA threshold simulation
18.0% → Enhanced alarm trigger validation
17.0% → High-deficiency simulation
This 34L 18.0% configuration is commonly selected when stronger alarm confirmation is required in a compact format.
