Methane (CH₄) 10,000 ppm + Oxygen (O₂) 20.9% Calibration Gas – Nitrogen Balance

Specifications and cylinder appearance may vary by cylinder size and production lot.

Common Uses: Calibration and bump testing of compatible methane and oxygen gas detection instruments requiring a 10,000 ppm Methane mixture with 20.9% Oxygen and nitrogen balance.

Always verify the required calibration gas concentrations, balance gas, cylinder connection, regulator, flow rate, and instrument response requirements, and follow the instrument manufacturer's calibration and bump-test procedures before use.

Hazardous Material Shipping

Calibration gas cylinders are regulated for transportation as hazardous materials and must be shipped in accordance with applicable carrier and hazardous-material regulations. Available shipping methods and charges may vary based on cylinder size, quantity, destination, and applicable HazMat requirements.

Lead Time

Please allow approximately 3 business days for order processing prior to shipment. Lead times may vary depending on availability and order quantity.

Non-Returnable Product

Calibration gas is non-returnable. Because calibration gas is a certified gas mixture with a limited shelf life, cylinders cannot be returned or exchanged after shipment.

Please verify the gas concentrations, balance gas, cylinder size, and connection before placing your order.

Important Regulator Compatibility: The cylinder connections differ by size. The 34L cylinder uses a CGA-600 connection, while the 103L cylinder uses a C-10 connection. Verify that your regulator matches the cylinder connection selected before ordering.
