Methane 1.0% (20% LEL)/ Oxygen 20.9%/ Nitrogen Calibration Gas

Methane 1.0% (20% LEL) / Oxygen 20.9% / Nitrogen Calibration Gas

The Methane 1.0% (20% LEL) / Oxygen 20.9% / Nitrogen Calibration Gas Cylinder is a certified gas mixture engineered for calibrating and bump testing compatible combustible gas and oxygen detectors. Containing 1.0% methane (20% of the Lower Explosive Limit), 20.9% oxygen, and balance nitrogen, this calibration gas provides a dependable reference standard for verifying gas detector performance before instruments are placed into service.

Widely used by industrial facilities, utility companies, wastewater treatment plants, manufacturing operations, oil and gas professionals, environmental contractors, and confined space safety teams, this calibration gas helps maintain reliable combustible gas monitoring while supporting workplace safety and regulatory compliance.

Verify Detector Accuracy with Confidence

Routine calibration and bump testing are essential for ensuring combustible gas detectors respond properly to methane hazards. This certified gas mixture helps verify sensor accuracy, identify calibration drift, confirm alarm activation, and maintain detector performance throughout the instrument's service life.

The included 20.9% oxygen concentration represents normal atmospheric oxygen conditions, allowing users to verify oxygen sensor performance while simultaneously testing methane detection using a single calibration gas cylinder.

Designed for Professional Safety Programs

Whether supporting confined space entry procedures, industrial maintenance programs, emergency response teams, municipal utilities, or environmental monitoring projects, this calibration gas provides consistent performance for routine gas detector maintenance and functional testing.
