Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This 4-gas calibration mixture is designed for calibration and bump testing of portable multi-gas detectors used in confined space monitoring, industrial hygiene programs, and hazardous atmosphere detection.
The certified mixture contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 1.62% (50% LEL LPG equivalent), and Oxygen (O₂) 18.0%, balanced with nitrogen. These concentrations allow technicians to verify detector response across multiple gas sensor channels used in portable safety monitors.
Supplied in a 44L aluminum calibration cylinder pressurized to 750 PSI, this gas mixture offers a portable calibration solution suitable for routine field verification of gas detectors used across industrial safety programs.
The C-10 valve connection supports compatibility with standard calibration regulators used with portable gas detection equipment.
