Product Description
34L Disposable 4-Gas Calibration Gas – 19.5% Oxygen Deficiency Verification
This 34 Liter disposable 4-gas calibration cylinder is designed for short-term projects, contractor work, and training programs requiring oxygen-deficiency alarm validation at 19.5% O₂.
Gas mixture includes:
-
Hydrogen Sulfide (H₂S) – 10 PPM
-
Carbon Monoxide (CO) – 50 PPM
-
Methane (CH₄) – 2.5% (50% LEL)
-
Oxygen (O₂) – 19.5%
-
Nitrogen Balance
The 19.5% oxygen concentration allows technicians to confirm that oxygen sensors activate properly at OSHA’s defined minimum safe limit, while simultaneously verifying toxic and combustible sensor channels.
The 500 PSI disposable aluminum cylinder provides practical convenience for lower-frequency calibration schedules and mobile safety kits.
