Product Description
CO 200 PPM / CH₄ 2.5% (50% LEL) / O₂ 19.0% Calibration Gas – 66L Cylinder
This calibration gas blend contains Carbon Monoxide (CO) 200 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 19.0%, balanced in nitrogen to simulate slightly reduced oxygen environments while maintaining accurate multi-gas detector calibration. Supplied in a 66L aluminum cylinder at 1150 PSI with a C-10 valve, this mixture is ideal for calibration scenarios requiring subtle oxygen variation from standard atmospheric conditions.
Cylinder & Mixture Details
- Cylinder Size: 66L (2.3 Cubic Feet)
- Cylinder Pressure: 1150 PSI
- Cylinder Material: Aluminum
- Valve Type: C-10

Applications & Use Cases
- Calibration in slightly reduced oxygen environments
- Detector response verification across oxygen thresholds
- Industrial hygiene and safety compliance testing
- Transitional calibration between standard and reduced O₂ conditions
Why This Gas Blend
- 200 PPM CO supports lower-range toxic gas calibration
- Methane at 50% LEL for combustible hazard simulation
- 19.0% oxygen provides a controlled deviation from atmospheric baseline
- Useful for fine-tuning detector response across oxygen ranges
