Product Description
66L 1150 PSI 4-Gas Calibration Cylinder – 15 PPM H₂S / 50 PPM CO / 18% Oxygen
This 4-gas calibration cylinder is engineered for facilities that program lower toxic alarm thresholds and require verification of moderate oxygen-deficiency response.
With hydrogen sulfide at 15 PPM and carbon monoxide at 50 PPM, this blend supports early-warning toxic detection strategies commonly implemented in regulated industrial and municipal environments.
Gas Composition Details
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 sensitive toxic channel calibration.
• 50 PPM CO supports lower CO alarm validation.
• 2.5% methane equals 50% LEL for combustible sensor accuracy testing.
• 18.0% oxygen creates a controlled deficiency atmosphere below OSHA’s 19.5% threshold.
This blend allows multi-channel calibration while reinforcing early alarm detection reliability.
