Product Description
CH₄ 2.5% (50% LEL) / O₂ 15.0% / Nitrogen (N₂) Balance Calibration Gas
Maintain reliable gas detector performance with CH₄ 2.5% (50% LEL) / O₂ 15.0% / Nitrogen (N₂) balance calibration gas, designed for calibration, bump testing, and preventative maintenance of portable and fixed gas detection systems. Supplied in a 680-liter aluminum cylinder with a 1800 PSI fill pressure and a CGA specific valve connection, this non-reactive calibration gas mixture provides stable, repeatable gas concentrations for dependable detector verification and long-term sensor performance.
Containing 2.5% methane (50% of the Lower Explosive Limit) and 15.0% oxygen, this specialty calibration gas mixture is ideal for verifying multi-gas detectors that simultaneously monitor combustible gases and oxygen levels. It helps ensure accurate sensor response in industrial environments where combustible gas detection and oxygen monitoring are both essential for worker safety and regulatory compliance.
Calibration Gas Composition
| Gas | Concentration |
|---|---|
| Methane (CH₄) | 2.5% (50% LEL) |
