Product Description
44L 750 PSI 4-Gas Calibration Gas – 17.0% Oxygen Deficiency Simulation
This mid-size 4-gas calibration cylinder is formulated for programs requiring strong oxygen-displacement alarm validation in a manageable, field-ready configuration.
Gas 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 blend simulates a significant deficiency condition to confirm detector activation under more demanding alarm scenarios.
Cylinder Configuration
Cylinder Volume: 44L (1.5 Cubic Feet)
Fill Pressure: 750 PSI
Valve Connection: C-10
Cylinder Material: Aluminum
Gas Reactivity: Reactive
The 750 PSI fill balances portability and calibration capacity for recurring field verification cycles.
Application Focus
• Confined space entry validation
• Oxygen alarm performance testing
• Routine bump test procedures
• Industrial hygiene compliance
• Combustible and toxic sensor verification
Methane at 2.5% equals 50% LEL for combustible sensor confirmation.
CO at 100 PPM supports typical low-alarm calibration settings.
Oxygen Level Framework
20.9% → Ambient baseline
19.0% → Early deficiency simulation
18.5% → OSHA threshold validation
18.0% → Enhanced deficiency testing
17.0% → High-deficiency confirmation
This 44L 17.0% configuration is selected when alarm systems must be validated under stronger displacement conditions without large cylinder deployment.
