Methane 1.75% / Oxygen 20.9% / Nitrogen Calibration Gas

Methane 1.75% / Oxygen 20.9% / Nitrogen Calibration Gas

The Methane 1.75% / Oxygen 20.9% / Nitrogen Calibration Gas Cylinder is a certified calibration gas mixture developed for calibrating and bump testing compatible combustible gas and oxygen detectors. Containing 1.75% methane, 20.9% oxygen, and balance nitrogen, this mixture provides a reliable reference standard for verifying gas detector accuracy, sensor response, and alarm functionality.

Used by industrial safety professionals, utilities, manufacturing facilities, wastewater treatment plants, oil and gas operations, chemical processors, and environmental contractors, this calibration gas supports routine detector maintenance while helping ensure personnel are protected in hazardous environments.

Dependable Calibration for Combustible Gas Detection

Routine calibration and functional bump testing are essential to maintaining dependable gas monitoring equipment. This certified methane calibration gas helps identify sensor drift, verify proper combustible gas response, confirm alarm activation, and ensure instruments continue operating within manufacturer specifications.

The included 20.9% oxygen concentration represents normal atmospheric oxygen conditions, allowing both methane and oxygen sensors to be verified during a single calibration procedure on compatible multi-gas detectors.

Built for Industrial Gas Detection Programs

Whether supporting confined space entry, facility maintenance, utility operations, environmental monitoring, emergency response, or industrial safety compliance programs, this calibration gas provides consistent performance for routine instrument verification and preventive maintenance.
