Product Description
CH₄ 1.0% (20% LEL) / Nitrogen (N₂) Balance Calibration Gas
Optimize gas detector performance with CH₄ 1.0% (20% LEL) / Nitrogen (N₂) balance calibration gas, formulated for calibration, bump testing, detector verification, and preventative maintenance of compatible portable and fixed gas detection systems. Supplied in a 221-liter disposable steel cylinder at 250 PSI with a CGA-165 valve connection, this non-reactive calibration gas mixture provides a defined methane concentration for verifying sensor response and maintaining detector accuracy.
Containing 1.0% methane (20% of the Lower Explosive Limit) with nitrogen as the balance gas, this calibration mixture is designed for compatible combustible gas detectors configured to monitor methane. Routine calibration with the appropriate gas standard helps verify sensor response, identify potential instrument drift, and support dependable methane monitoring in industrial and occupational environments.
Calibration Gas Composition
| Gas | Concentration |
|---|---|
| Methane (CH₄) | 1.0% (20% LEL) |
| Balance Gas | Nitrogen (N₂) |
This methane calibration gas is suitable for industrial hygienists, EHS professionals, maintenance technicians, safety managers, and environmental specialists maintaining compatible combustible gas detection equipment. Common applications include oil & gas, petrochemical processing, manufacturing, mining, wastewater treatment, utilities, chemical processing, confined space entry, and other industrial environments where accurate methane detection is critical.

The 221-liter disposable steel cylinder provides a higher-capacity calibration gas supply for facilities and service operations with recurring detector calibration requirements. Its 250 PSI fill pressure and CGA-165 connection support compatible calibration equipment used for bump testing, detector verification, sensor response checks, and preventative maintenance while reducing the need for frequent cylinder replacement compared with smaller portable cylinders.
Always confirm the required calibration concentration, regulator, flow rate, and valve compatibility specified by the gas detector manufacturer before use.
If your application requires a different methane concentration, LEL percentage, cylinder size, valve configuration, or specialty gas blend, we manufacture custom calibration gas mixtures for a wide variety of gas detection applications. Contact our team for a quick custom quote if your required mixture is not available in our e-commerce store.
