Product Description
Technical 4-Gas Calibration Standard – 17.0% Oxygen | 120L 1050 PSI
This 4-gas calibration mixture is formulated for validation of multi-gas detectors operating in regulated confined space environments where deeper oxygen displacement simulation is required.
Gas Concentration Summary
Hydrogen Sulfide (H₂S): 25 PPM
Carbon Monoxide (CO): 100 PPM
Methane (CH₄): 2.5% (50% LEL)
Oxygen (O₂): 17.0%
Balance: Nitrogen
The 17.0% oxygen concentration is used to confirm detector alarm activation under significant deficiency conditions rather than minimum-threshold verification.
Cylinder Configuration Data
Volume: 120L (4.2 Cubic Feet)
Pressure Rating: 1050 PSI
Valve Connection: C-10
Cylinder Construction: Aluminum
Reactivity Classification: Reactive
The 1050 PSI fill pressure supports extended calibration duration and is suited for structured calibration stations with continuous servicing schedules.
Calibration Integrity Focus
Unlike threshold-level oxygen blends, 17.0% oxygen is used to:
• Validate sensor responsiveness under deeper displacement
• Confirm alarm escalation reliability
• Test detector recovery behavior
• Verify system stability after sustained deficiency exposure
Methane at 2.5% represents 50% LEL for controlled combustible sensor verification.
Carbon monoxide at 100 PPM supports standard toxic gas calibration points.
Program Implementation
This configuration is typically implemented in:
• Industrial processing facilities
• Energy and utilities sectors
• Municipal confined space operations
• Manufacturing safety departments
• High-usage detector maintenance environments
