Product Description
60L 4-Gas Calibration Blend – 15 PPM H₂S / 50 PPM CO with 18% Oxygen
This 4-gas calibration cylinder is configured for organizations that prioritize lower toxic alarm thresholds and early detection strategies.
By combining reduced H₂S and CO concentrations with controlled oxygen displacement at 18.0%, this blend verifies detector response across toxic, combustible, and oxygen channels without introducing severe deficiency conditions.
Gas Blend Breakdown
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 validates early-stage toxic detection.
• 50 PPM CO confirms lower CO alarm programming.
• 2.5% methane equals 50% LEL for combustible sensor calibration.
• 18.0% oxygen simulates a controlled deficiency atmosphere below OSHA’s 19.5% benchmark.
This combination supports balanced calibration where sensitivity and stability are equally important.
