Product Description
Hydrogen Sulfide (H₂S) 10 PPM / Carbon Monoxide (CO) 35 PPM / Methane (CH₄) 0.5% (10% LEL) / Oxygen (O₂) 18.0% Calibration Gas – 34L Cylinder
Maintaining accurate readings from portable gas monitors requires a stable, certified calibration gas mixture. This 4-gas calibration blend combines Hydrogen Sulfide, Carbon Monoxide, Methane, and Oxygen in balanced concentrations designed specifically for bump testing and calibration of multi-gas detectors used in industrial safety environments.
The compact 34L disposable aluminum cylinder provides a convenient solution for technicians performing routine detector maintenance, sensor verification, and safety compliance checks across worksites, refineries, utilities, and confined space entry operations.
