Product Description
CH₄ 2.5% (50% LEL) / Nitrogen (N₂) Balance Calibration Gas
Keep your gas detection equipment performing at its best with CH₄ 2.5% (50% LEL) / Nitrogen (N₂) balance calibration gas, engineered for calibration, bump testing, and preventative maintenance of portable and fixed gas detection systems. Supplied in a 66-liter refillable aluminum cylinder with a 1150 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), this calibration gas is specifically formulated to verify combustible gas detectors that monitor methane concentrations in hazardous industrial environments where precise LEL measurements are essential for worker safety, regulatory compliance, and reliable methane monitoring.
