MSA Econo-Cal RP Reactive Gas Calibration Cylinder 34 L 1.45% CH4 / 15% O2 / CO / H2S / Balance N2

The MSA Safety Econo-Cal RP Reactive Gas Calibration Cylinder delivers precise 4- and 5-gas detector calibration with a 34-liter capacity. This NIST-traceable gas mixture contains 1.45% methane, 15% oxygen, 60 ppm carbon monoxide, and 20 ppm hydrogen sulfide with nitrogen balance. The reduced pressure (RP) model provides reliable calibration standards for workplace gas detection equipment.

Built to DOT Class 2 compressed gas specifications, this cylinder requires hazmat shipping protocols. The reactive gas mixture ensures accurate calibration across multiple gas types in a single cylinder, reducing inventory needs and simplifying calibration procedures. Each cylinder provides NIST-traceable accuracy for compliance with gas detection calibration requirements.

This calibration gas works with multi-gas detectors commonly used in confined spaces, industrial facilities, and construction sites where methane, oxygen deficiency, carbon monoxide, and hydrogen sulfide monitoring is critical. The 34-liter capacity provides multiple calibrations before replacement is needed.
