Product Description
CH₄ 2.5% (50% LEL) / Air Balance Calibration Gas
Verify methane detector performance with CH₄ 2.5% (50% LEL) / Air balance calibration gas, formulated for calibration, detector verification, and preventative maintenance of compatible combustible gas detection systems. Supplied in a 34-liter disposable steel cylinder at 500 PSI with a CGA-600 valve connection, this non-reactive calibration gas mixture provides a defined methane concentration for verifying sensor response and maintaining detector accuracy.
Containing 2.5% methane (CH₄), equivalent to 50% of the Lower Explosive Limit (LEL), with air as the balance gas, this calibration mixture is intended 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.
