Product Description
CH₄ 1.5% (30% LEL) / O₂ 19.0% / Nitrogen (N₂) Balance Calibration Gas
Verify the accuracy of your gas detection equipment 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. Packaged in a 34-liter disposable steel cylinder with a 500 PSI fill pressure and a CGA-600 valve connection, this non-reactive calibration gas mixture provides precise, repeatable gas concentrations for dependable detector verification in industrial applications.
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 calibrate combustible gas detectors used in oil & gas, manufacturing, wastewater treatment, utilities, chemical processing, confined space entry, and other industrial environments where reliable gas monitoring is essential.
