Product Description
116L 4-Gas Calibration Cylinder – 15 PPM H₂S / 50 PPM CO with 18% Oxygen
This 116L 4-gas calibration blend is configured for structured safety programs operating lower toxic alarm thresholds while validating controlled oxygen-deficiency response.
By combining sensitive toxic concentrations with moderate oxygen displacement, this cylinder supports repeatable multi-gas detector verification in centralized servicing environments.
Gas Composition Profile
Hydrogen Sulfide (H₂S): 15 PPM
Carbon Monoxide (CO): 50 PPM
Methane (CH₄): 2.5% (50% LEL)
Oxygen (O₂): 18.0%
Balance Gas: Nitrogen
• 15 PPM H₂S confirms early toxic alarm sensitivity.
• 50 PPM CO aligns with conservative CO setpoints.
• 2.5% methane equals 50% LEL for combustible channel validation.
• 18.0% oxygen verifies deficiency response below OSHA’s 19.5% threshold.
This blend validates all four sensor channels in a single calibration cycle.
Cylinder Specifications
Cylinder Capacity: 116L (4.0 Cubic Feet)
Fill Pressure: 1000 PSI
Valve Type: C-10
Cylinder Material: Aluminum
Gas Reactivity: Reactive
The 1000 PSI fill provides stable output with predictable service intervals for organized maintenance programs.
Common Use Cases
• Industrial hygiene departments
• Utility and wastewater operations
• Manufacturing facilities
• Confined space entry programs
• Detector fleet servicing stations
The 116L configuration supports high-throughput calibration without the maximum-pressure tier positioning of 120L cylinders.
