Product Description
44L 4-Gas Calibration Cylinder – 100 PPM CO with 18% Oxygen Deficiency Simulation
This 4-gas calibration blend is engineered for facilities operating conservative H₂S thresholds and standard carbon monoxide alarm setpoints while requiring oxygen-deficiency validation.
With oxygen reduced to 18.0%, this cylinder confirms toxic, combustible, and oxygen channel performance under realistic confined-space alarm conditions.
Gas Composition Profile
Hydrogen Sulfide (H₂S): 15 PPM
Carbon Monoxide (CO): 100 PPM
Methane (CH₄): 2.5% (50% LEL)
Oxygen (O₂): 18.0%
Balance Gas: Nitrogen
• 15 PPM H₂S supports early toxic alarm confirmation.
• 100 PPM CO aligns with common industrial CO alarm thresholds.
• 2.5% methane equals 50% LEL for combustible sensor calibration.
• 18.0% oxygen simulates deficiency below OSHA’s 19.5% benchmark.
This configuration allows technicians to verify all four channels in a single servicing cycle.

The 44L format offers a balance of portability and service duration for mobile technicians and mid-volume servicing programs.
Recommended Applications
• Confined space compliance programs
• Utility and municipal operations
• Wastewater treatment facilities
• Industrial hygiene departments
• Field-based detector servicing
This size is commonly selected for portable servicing without moving into fleet-tier volume.
