Product Description
CO 300 PPM / CH₄ 1.45% (58% LEL Pentane Sim.) / O₂ 15.0% Calibration Gas – 221L Cylinder
This calibration gas blend contains Carbon Monoxide (CO) 300 PPM, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0%, balanced in nitrogen to simulate pentane-based detector response. Supplied in a 221L steel cylinder at 250 PSI with a CGA-165 valve, this disposable configuration is designed for extended calibration use while maintaining manageable pressure and handling.
Cylinder & Mixture Details
- Cylinder Size: 221L (7.5 Cubic Feet)
- Cylinder Pressure: 250 PSI
- Cylinder Material: Steel
- Valve Type: CGA-165
