Product Description
116L 4-Gas Calibration Cylinder – 250 PPM CO with 18% Oxygen Deficiency Simulation
This 4-gas calibration blend is engineered for facilities requiring elevated carbon monoxide validation combined with controlled oxygen-deficiency alarm confirmation.
With CO at 250 PPM and oxygen reduced to 18.0%, this mixture verifies toxic, combustible, and oxygen sensor performance under demanding confined-space conditions.
Gas Composition Profile
Hydrogen Sulfide (H₂S): 15 PPM
Carbon Monoxide (CO): 250 PPM
Methane (CH₄): 2.5% (50% LEL)
Oxygen (O₂): 18.0%
Balance Gas: Nitrogen
• 15 PPM H₂S confirms lower H₂S alarm programming.
• 250 PPM CO validates high CO alarm setpoints.
• 2.5% methane equals 50% LEL for combustible channel calibration.
• 18.0% oxygen simulates deficiency below OSHA’s 19.5% benchmark.
This blend allows technicians to stress CO response while validating oxygen depletion alarms within a single servicing 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 and predictable service intervals for structured fleet calibration programs.
Ideal For
• Industrial hygiene departments
• Confined space compliance programs
• Energy and combustion-heavy facilities
• Utility and wastewater operations
• Centralized multi-detector servicing stations
The 116L configuration supports high-volume calibration without the maximum-pressure tier positioning of 120L cylinders.
