Product Description
CO 250 PPM / CH₄ 2.5% (50% LEL) / O₂ 17.0% Calibration Gas – 120L Cylinder
This calibration gas blend contains Carbon Monoxide (CO) 250 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 17.0%, balanced in nitrogen to simulate oxygen-deficient environments while maintaining accurate multi-gas detector calibration. Supplied in a 120L aluminum cylinder at 1050 PSI with a C-10 valve, this mixture is designed for routine calibration in controlled, reduced oxygen conditions.
Cylinder & Mixture Details
- Cylinder Size: 120L (4.2 Cubic Feet)
- Cylinder Pressure: 1050 PSI
- Cylinder Material: Aluminum
- Valve Type: C-10

Applications & Use Cases
- Calibration in oxygen-deficient environments
- Confined space safety testing and validation
- Industrial hygiene compliance monitoring
- Detector performance testing under reduced oxygen conditions
Why This Gas Blend
- 250 PPM CO supports mid-range toxic gas calibration
- Methane at 50% LEL for combustible hazard simulation
- Lower oxygen level (17.0%) increases realism for confined environments
- Mid-capacity cylinder supports extended but manageable use
