Product Description
CH₄ 1.0% (20% LEL) / Nitrogen (N₂) Balance Calibration Gas
Calibrate gas detection equipment with CH₄ 1.0% (20% LEL) / Nitrogen (N₂) balance calibration gas, formulated for calibration, bump testing, and routine maintenance of portable and fixed gas detection systems. Supplied in a 680-liter aluminum cylinder with a 1800 PSI fill pressure and CGA specific valve connection, this non-reactive custom gas mixture provides a defined methane concentration for verifying detector response and maintaining measurement accuracy.
Containing 1.0% methane (20% of the Lower Explosive Limit) with nitrogen as the balance gas, this calibration mixture is designed for combustible gas detectors configured to monitor methane. Routine calibration with the appropriate certified gas concentration helps verify that detector sensors respond correctly before instruments are relied upon in industrial and occupational environments.
Calibration Gas Composition
| Gas | Concentration |
|---|---|
| Methane (CH₄) | 1.0% (20% LEL) |
| Balance Gas | Nitrogen (N₂) |
This methane calibration gas can be used with compatible gas detection equipment across industrial hygiene, occupational safety, oil and gas, petrochemical processing, manufacturing, mining, wastewater treatment, utilities, chemical processing, confined space programs, and other applications requiring methane or combustible gas monitoring.
Cylinder Specifications

The 680-liter cylinder provides a high-capacity calibration gas supply suited to facilities, laboratories, service operations, and maintenance programs with frequent detector calibration requirements. The larger gas volume can reduce cylinder change frequency while supporting recurring calibration, bump testing, sensor verification, and preventative maintenance procedures.
Always confirm the required calibration concentration, regulator, flow rate, and valve compatibility specified by the gas detector manufacturer before use.
If you require another methane concentration, cylinder size, valve configuration, or specialty gas mixture, custom calibration gases are available for a wide variety of gas detector applications. Contact us for a quick quote when the calibration gas you need is not listed in our ecommerce store.
