Product Description
CH₄ 1.45% (29% LEL) / O₂ 15.0% / Nitrogen (N₂) Balance Calibration Gas
Protect the accuracy of your gas detection equipment with this CH₄ 1.45% (29% LEL) / O₂ 15.0% / Nitrogen (N₂) balance calibration gas, developed for calibration, bump testing, and preventative maintenance of portable and fixed gas detection systems. Packaged 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 dependable detector verification across demanding industrial applications.
Calibration Gas Composition
| Gas | Concentration |
|---|---|
| Methane (CH₄) | 1.45% (29% LEL) |
| Oxygen (O₂) | 15.0% |
| Balance Gas | Nitrogen (N₂) |
This methane calibration gas is trusted by industrial hygienists, EHS professionals, maintenance technicians, and safety managers to calibrate combustible gas detectors used throughout oil & gas, manufacturing, wastewater treatment, chemical processing, utilities, mining, confined space entry, and other industrial environments where reliable gas monitoring is critical.
