Product Description
116L 1000 PSI 4-Gas Calibration Gas – 18.0% Oxygen Deficiency Validation
This high-capacity 4-gas calibration cylinder is designed for safety programs requiring repeatable, structured oxygen-deficiency alarm verification.
Gas Blend Profile
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 atmosphere for validating detector alarms below OSHA’s 19.5% oxygen requirement.
Cylinder Specifications
Volume: 116L (4.0 Cubic Feet)
Fill Pressure: 1000 PSI
Valve Connection: C-10
Cylinder Material: Aluminum
Gas Classification: Reactive
The 1000 PSI pressure rating supports compatibility with common fixed-flow regulators used in calibration stations while delivering extended service intervals.
Designed For
• Multi-gas detector fleet management
• Scheduled bump test cycles
• Industrial hygiene compliance audits
• Centralized calibration benches
• Confined space safety programs
Methane at 2.5% equals 50% LEL for combustible sensor performance validation.
CO at 100 PPM supports standard low-alarm setpoint calibration.
Oxygen Tier Differentiation
20.9% → Ambient reference air
19.0% → Mild deficiency testing
18.5% → OSHA threshold simulation
18.0% → Enhanced controlled deficiency
17.0% → Aggressive deficiency validation
This 116L 1000 PSI configuration balances capacity and regulator compatibility for structured safety operations.
