Methane 3.0%/ Oxygen 20.9%/ Nitrogen Calibration Gas

Methane 3.0% / Oxygen 20.9% / Nitrogen Calibration Gas

The Methane 3.0% / Oxygen 20.9% / Nitrogen Calibration Gas Cylinder is a certified calibration gas mixture formulated for calibrating and bump testing compatible combustible gas and oxygen detectors. Containing 3.0% methane, 20.9% oxygen, and balance nitrogen, this calibration gas provides a stable reference standard for verifying gas detector accuracy, sensor performance, and alarm functionality before instruments are placed into service.

Designed for industrial safety professionals, utilities, manufacturing facilities, chemical plants, wastewater treatment operations, oil and gas companies, mining operations, and emergency response teams, this gas mixture helps maintain dependable gas detection systems and supports workplace safety programs.

Reliable Calibration for Combustible Gas Monitoring

Routine calibration is critical for ensuring combustible gas detectors accurately respond to methane concentrations. This certified calibration gas helps identify sensor drift, verify proper alarm activation, and confirm detector performance according to manufacturer specifications. Regular bump testing also provides confidence that gas monitors are ready for use in hazardous environments.

The included 20.9% oxygen concentration represents normal atmospheric oxygen conditions, allowing compatible multi-gas instruments to verify both combustible gas and oxygen sensors during a single calibration procedure.

Built for Industrial Gas Detection Programs

Whether used for confined space entry, industrial maintenance, utility inspections, environmental monitoring, refinery operations, or preventive maintenance programs, this calibration gas delivers dependable performance for routine gas detector verification.
