4-Gas Calibration Mix: 50 PPM CO, 50% LEL CH4, 25 PPM H2S, 19% O2 / Balance N2 (58L Aluminum Cylinder)
Part Number: GASCO 58L-418
Product Overview
The GASCO 58L-418 is a high-accuracy, 4-gas quad calibration mixture blended into a lightweight 58-liter aluminum cylinder. Formulated with 50 PPM Carbon Monoxide (CO), 50% LEL Methane (CH4), 25 PPM Hydrogen Sulfide (H2S), and 19.0% Oxygen (O2) balance Nitrogen (N2), this mixture is designed specifically for instruments and safety protocols requiring a 19.0% Oxygen span point.
Manufactured in the USA to rigorous NIST-traceable analytical standards, each cylinder is equipped with an industry-standard C-10 connection (5/8"-18 UNF) rated to 500 PSI. The cylinder label includes an integrated QR code for immediate, on-site retrieval of Safety Data Sheets (SDS) and NIST Traceable Certificates of Analysis via any mobile device.
