Product Description
CO 300 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.9% Calibration Gas – 221L Cylinder
This extended-capacity calibration gas blend features Carbon Monoxide (CO) 300 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 20.9%, balanced in nitrogen for dependable gas detector calibration. Packaged in a 221L steel cylinder at 250 PSI with a CGA-165 valve, this disposable option is ideal for teams needing longer use intervals without handling high-pressure refillable cylinders.
