This 34 L aluminum calibration gas cylinder is designed for accurate calibration of multigas detection instruments. The certified gas mixture contains methane (CH₄) 1.45%, oxygen (O₂) 15%, carbon monoxide (CO) 60 ppm, and hydrogen sulfide (H₂S) 20 ppm. Prepared gravimetrically using NIST-traceable weights, each cylinder ensures precise concentration values to support reliable instrument performance and regulatory compliance.
