Product Description
GASCO 58L-421 | X05NI79CP5844Y5 | 100 PPM Carbon Monoxide 2.5% CH4 (50% LEL) Methane 25 PPM Hydrogen Sulfide 18% Oxygen in Nitrogen contained in a 58 Liter Aluminum Cylinder, Cylinder connection C-10 5/8"-18 UNF, Calibration Certificate NIST, Made in the USA
The GASCO 58L-421 | X05NI79CP5844Y5 is a certified multi-gas calibration standard formulated for bump testing and span calibrations of portable and stationary 4-gas atmospheric monitors. Blended with precision to meet stringent industrial hygiene requirements, this reactive gas mixture contains 100 PPM Carbon Monoxide, 2.5% Methane (50% LEL), 25 PPM Hydrogen Sulfide, and 18.0% Oxygen balanced in high-purity Nitrogen.
Housed in a rugged, portable disposable 58-liter aluminum cylinder, this cylinder features an industry-standard C-10 valve (5/8"-18 UNF) compatible with standard fixed-flow, on-demand demand flow (DFR), and dial-a-flow calibration regulators. Every cylinder includes an individual analytical NIST-traceable Certificate of Analysis available via QR Code on label, ensuring audit compliance and regulatory traceability for military, environmental, municipal, and industrial field teams. Manufactured and bottled entirely in the United States.
