Product Description
CH₄ 1.5% (30% LEL) / O₂ 19.0% / Nitrogen (N₂) Balance Calibration Gas
Improve gas detector reliability with this CH₄ 1.5% (30% LEL) / O₂ 19.0% / Nitrogen (N₂) balance calibration gas, specifically formulated for calibration, bump testing, and preventative maintenance of portable and fixed gas detection systems. Supplied in a 221-liter disposable steel cylinder with a 250 PSI fill pressure and a CGA-165 valve connection, this non-reactive calibration gas mixture provides stable, repeatable gas concentrations for accurate detector verification in demanding 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 widely used by industrial hygienists, EHS professionals, maintenance technicians, and safety managers to verify combustible gas detectors in oil & gas operations, manufacturing facilities, wastewater treatment plants, chemical processing, utilities, confined space programs, and other industrial applications where dependable gas monitoring is essential.
