Product Description
60L 1000 PSI 4-Gas Calibration Gas – 18.0% Oxygen Deficiency Blend
This 4-gas calibration cylinder is formulated for structured oxygen-deficiency simulation in confined space and industrial compliance programs.
Blend Composition
Hydrogen Sulfide (H₂S) – 25 PPM
Carbon Monoxide (CO) – 100 PPM
Methane (CH₄) – 2.5% (50% LEL)
Oxygen (O₂) – 18.0%
Balance – Nitrogen
This 18.0% oxygen concentration provides a deeper deficiency condition than 18.5%, supporting alarm trigger verification below OSHA’s 19.5% requirement.
Cylinder Configuration
Cylinder Volume: 60L (2.1 Cubic Feet)
Fill Pressure: 1000 PSI
Valve Connection: C-10
Cylinder Construction: Aluminum
Gas Classification: Reactive
The 1000 PSI fill provides extended bump test capacity while remaining compatible with common fixed-flow regulators used in portable calibration kits.
Intended Applications
• Multi-gas monitor calibration
• Confined space oxygen-deficiency validation
• Industrial hygiene compliance programs
• Fleet detector maintenance cycles
• Combustible and toxic gas sensor verification
Methane at 2.5% equals 50% LEL, providing controlled combustible sensor testing.
CO at 100 PPM supports typical low-alarm verification settings.
Oxygen Tier Positioning
20.9% → Ambient simulation
19.0% → Mild deficiency
18.5% → OSHA threshold simulation
18.0% → Controlled enhanced deficiency
17.0% → Aggressive deficiency simulation
This 18.0% configuration is commonly selected for programs requiring stronger alarm validation without extreme oxygen displacement.
