Product Description
CH₄ 2.5% (50% LEL) / O₂ 12.0% / Nitrogen (N₂) Balance Calibration Gas
Depend on consistent gas detector performance with this CH₄ 2.5% (50% LEL) / O₂ 12.0% / Nitrogen (N₂) balance calibration gas, engineered for calibration, bump testing, and preventative maintenance of portable and fixed gas detection systems. Housed in a 17-liter disposable steel cylinder with a 240 PSI fill pressure and a CGA-600 valve connection, this non-reactive calibration gas mixture provides reliable, repeatable concentrations for detector verification across demanding industrial environments.
Calibration Gas Composition
| Gas | Concentration |
|---|---|
| Methane (CH₄) | 2.5% (50% LEL) |
| Oxygen (O₂) | 12.0% |
| Balance Gas | Nitrogen (N₂) |
This methane calibration gas is ideal for verifying combustible gas detectors used by industrial hygienists, EHS professionals, maintenance technicians, and safety managers working in oil & gas, manufacturing, wastewater treatment, utilities, chemical processing, confined space operations, and other workplaces where accurate gas monitoring is essential.
