Product Description
CH₄ 1.5% (30% LEL) / O₂ 19.0% / Nitrogen (N₂) Balance Calibration Gas
Support reliable gas detector performance with this CH₄ 1.5% (30% LEL) / O₂ 19.0% / Nitrogen (N₂) balance calibration gas, formulated for calibration, bump testing, and preventative maintenance of portable and fixed gas detection systems. Supplied in a 120-liter aluminum cylinder with a 1050 PSI fill pressure and a C-10 valve connection, this non-reactive calibration gas mixture provides stable, repeatable gas concentrations for accurate 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, manufacturing, wastewater treatment, utilities, chemical processing, confined space entry, and other industrial settings where dependable gas monitoring is essential.
