The MSA Calibration Testing Gas Cylinder 10058172 is a 34 L certified calibration gas cylinder containing a four-gas mixture of 2.5% methane (CH₄), 15% oxygen (O₂), 60 ppm carbon monoxide (CO), and 10 ppm nitrogen dioxide (NO₂). Designed for calibrating compatible gas detection instruments, MSA calibration gas mixtures are prepared gravimetrically using NIST-traceable weights, with the lot number and nominal gas constituent values identified on the cylinder. This specific cylinder provides a defined multi-gas mixture for calibration and testing applications.

Key Features

Four-gas calibration mixture: Combines methane, oxygen, carbon monoxide, and nitrogen dioxide in one cylinder.
Certified gas mixture: MSA calibration gases are prepared gravimetrically using NIST-traceable weights.
Cylinder identification: Lot number and nominal values of the gas constituents are specified on the cylinder.
34 L capacity: Provides a compact calibration gas format for compatible gas detection equipment.

Intended Use

Designed for calibration and testing of compatible gas detection instruments in applications such as:

Confined space
General industry
Oil and gas
Mining
Utilities
