Product Description
CO 200 PPM / CH₄ 2.5% (50% LEL) / O₂ 19.0% Calibration Gas – 120L 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 120L aluminum cylinder at 1050 PSI with a C-10 valve, this mixture is ideal for routine calibration where controlled oxygen variation is required.
Cylinder & Mixture Details
- Cylinder Size: 120L (4.2 Cubic Feet)
- Cylinder Pressure: 1050 PSI
- Cylinder Material: Aluminum
