Product Description
CH₄ 1.0% (20% LEL) / O₂ 18.0% / Nitrogen (N₂) Balance Calibration Gas
Support dependable gas detector performance with this CH₄ 1.0% (20% LEL) / O₂ 18.0% / Nitrogen (N₂) balance calibration gas, formulated for calibration, bump testing, and preventative maintenance of portable and fixed gas detection systems. Packaged in a 680-liter aluminum cylinder with a 1800 PSI fill pressure and a CGA-specific valve connection, this non-reactive calibration gas mixture provides stable, repeatable concentrations for accurate detector verification in demanding industrial environments.
Calibration Gas Composition
| Gas | Concentration |
|---|---|
| Methane (CH₄) | 1.0% (20% LEL) |
| Oxygen (O₂) | 18.0% |
| Balance Gas | Nitrogen (N₂) |
This methane calibration gas is relied upon by industrial hygienists, EHS professionals, maintenance technicians, and safety managers to calibrate combustible gas detectors across oil & gas, manufacturing, wastewater treatment, mining, utilities, chemical processing, and confined space applications where accurate gas monitoring is essential for worker safety.
