Product Description
CH₄ 1.5% (30% LEL) / O₂ 19.0% / Nitrogen (N₂) Balance Calibration Gas
Achieve dependable gas detector accuracy with this CH₄ 1.5% (30% LEL) / O₂ 19.0% / Nitrogen (N₂) balance calibration gas, developed for calibration, bump testing, and preventative maintenance of portable and fixed gas detection systems. Supplied in a 680-liter aluminum cylinder with an 1800 PSI fill pressure and a CGA-specific valve connection, this non-reactive calibration gas mixture delivers stable, repeatable concentrations for reliable detector verification in industrial environments.
Calibration Gas Composition
| Gas | Concentration |
|---|---|
| Methane (CH₄) | 1.5% (30% LEL) |
| Oxygen (O₂) | 19.0% |
| Balance Gas | Nitrogen (N₂) |
This methane calibration gas is commonly used by industrial hygienists, EHS professionals, maintenance technicians, and safety managers to verify combustible gas detectors in oil & gas facilities, chemical processing plants, manufacturing operations, wastewater treatment facilities, utilities, confined space entry programs, and other applications where accurate gas monitoring is critical.
