Product Description
CH₄ 2.5% (50% LEL) / O₂ 15.0% / Nitrogen (N₂) Balance Calibration Gas
Verify reliable gas detector performance with CH₄ 2.5% (50% LEL) / O₂ 15.0% / Nitrogen (N₂) balance calibration gas, engineered for calibration, bump testing, and preventative maintenance of portable and fixed gas detection systems. Supplied in a 120-liter refillable aluminum cylinder with a 1050 PSI fill pressure and a C-10 valve connection, this non-reactive calibration gas mixture provides stable, repeatable gas concentrations for dependable detector verification and long-term sensor accuracy.
Containing 2.5% methane (50% of the Lower Explosive Limit) and 15.0% oxygen, this specialty calibration gas mixture is designed to verify multi-gas detectors that simultaneously monitor combustible gases and oxygen levels. It helps ensure accurate sensor response in industrial environments where reliable methane and oxygen monitoring are essential for worker safety, confined space entry, and regulatory compliance.
